When someone named Spammy emails you, you have a choice: flag as a phishing threat, or read in entirety? Well, we do get a kick out of seeing the moniker appear in our mailbox, from a listener whose skewering takes leave us chuckling every time. While most emailers use the show email to send questions, Spammy mostly offers witty commentary with no indication of a need for help and gives off the sense that he's seen it all. But this week, we've got a real honest-to-goodness question from the man. We're assuming it's a man. So the guys take on a comment/question related to the Philips Hue light bulbs and bars that have been mentioned previously on the show, which leads to a longer discussion about switch-mode and other noise in the listening room. The album recommendation this week comes from Darren's library as an old favorite.  This podcast is powered by CommonGround Cables Whisper power cable.

By popular demand, we present the new lost Dunlavy episode. Longtime listeners know that Darren and Duncan originally recorded 10 podcasts before publishing the very first one, as practice. One of those, referenced in early talks about the guys' dearly beloved Dunlavy speakers, was a thorough explanation of how they landed them for free, and insights gleaned from owning them. As requested, the guys do another complete Dunlavy-focused episode, but this time with new insights and a lot more info about the eponymous designer, John Dunlavy. The album recommendation pulls out a gem from a very talented young person's already swelling discography.  This podcast is powered by CommonGround Cables Whisper power cable.

In this episode, the pros and cons of the integrated amplifier are covered in typical Hifi Podcast style. Darren shares impressions and experience from the perspective of a designer, and both guys try to frame the situations where the integrated approach is either better or... not better. This week's questions share a common theme which takes Duncan back into recording engineer jibber jabber, and the solo viola de gamba performance as the album of the week is a can't miss.  This podcast is powered by CommonGround Cables Whisper power cable.

In this episode of The Hifi Podcast, hosts Darren and Duncan reflect on what motivates each to work in the industry and try their best to bring something new to the scene. Darren talks about his evolution in amplifier design, why he puts effort into discovering unique and new topologies and what motivates him these days after many circuits discovered. Duncan discusses how his upbringing inspires him to design cable products that bring the listener closer to an experience which places the musician on a personal level, and why that's a place of comfort for him.

With apologies for the delay, and for the audio which was nearly impossible to fix, the guys are back to answer a question from listener Rob Shrode. This episode is about the idea of a special price point threshold in each product category above which one can expect substantial performance improvement compared to below the threshold. As usual, it's not as simple a topic as it seems. The recommended album of the week is the eponymous debut from a brand new, hotshot-laden folk and bluegrass troupe assembled by the always impressive Chris Eldridge.  This podcast is powered by CommonGround Cables Whisper power cable.

Darren answers a question that has been in Duncan's mind for a while: What does Bridge Tied Load or BTL mean as it relates to amplifier design? The guys answer a question about properly powering a big set of Dunlavy speakers from a listener who stumbled across a big pair for a great price. The album of the week is only found on Bandcamp, and it features a couple acoustic virtuosos Duncan has followed for years.  This podcast is powered by CommonGround Cables Whisper power cable.

The show is back after a week break to deal with Duncan's Covid bout and the installation of PS Audio's new speakers at Darren's house. Questions were stacking up, so the guys took this week to pick their favorites and deliver an all-questions episode. After a check-in with a listener suffering from "tweakitis AKA restless audiophile syndrome," the guys talk about live versus recorded sound, tall speakers in a low-ceiling room, bypassing binding posts and more. This week's album comes from a pair of brothers in Switzerland whose jazz influences vary from Balkan to British to Brazilian.  This podcast is powered by CommonGround Cables Whisper power cable.

In this episode, the guys explore the reasons behind why some products -- mostly preamplifiers -- invert the signal phase. Darren explains that it's a decent reason behind the practice, and how to adjust to it in your system if you've got a piece of gear that does this. Earlier on, a question about a difficult room setup is fully discussed, offering reasons behind why the space is challenging, and options for mitigating its problems for best sound.

It's been a hell of a week here in Colorado, and after the fires and the fallout, the idea of how to protect your hifi system from danger and disaster seemed like an appropriate topic for this week's podcast. In this episode, Darren and Duncan discuss inrush currents and voltage spikes associated with some of the problems Mother Nature can throw at you, as well as flooding and more, and they offer ways to protect your beloved gear in the event that the worst comes to reality. The album of the week is an exciting one for Duncan, featuring a new album he mastered by a band he's truly fond of.  This podcast is powered by CommonGround Cables Whisper power cable.

Just about a year ago, a listener in Brooklyn, NY reached out with some ideas about building an all-Klipsch-Heritage-based dancehall and party space in the basement of his new house. In the year since, he got right to it, wasting no time and creating a space that his producer friends and he believe puts on some of the best-sounding dance parties in the whole region. In this episode, he checks back in with a few more questions and a ton of information about the year of parties that has Darren and Duncan wishing they were New Yorkers, if just to catch one of these events. Replete with a 1000-watt fog machine, a police beacon light and an upstairs Hifi system area for folks to take a "break from the basement beating," this place sounds absolutely incredible. Later in the episode, this week's album recommendation is a recent release, it's a bit more well known, it features incredible music and is a real test piece for any hifi system.  This podcast is powered by CommonGround Cables Whisper power cable.

As audiophiles, we listen in many different styles and sizes of rooms. Our spaces to setup well-tuned systems are, more often than not, the only ones we're given to work with. On the other side of the coin, sometimes it's the gear we already have which tells us what kind of space it should be in, and more specifically, how close we should listen. In this episode, Darren and Duncan talk about the pros and cons of nearfield, midfield and farfield listening as it relates to speaker type and sonic presentation. And this being the thick of the holiday season, not one, but two album recommendations round out the show in the annual music genre we know and love so well.  This podcast is powered by CommonGround Cables Whisper power cable.

The HiFi Podcast is back with a tech-centric take on FM Radio, answering a listener question and delving into why so many audiophiles gravitate toward it as a favorite source. As so many conversations do, this one meanders toward noise and distortion, but Darren's take on the loveliness of the sound of FM may surprise you.

Welcome back! In this episode, Darren, designer of an amplifier that TAS just named "2021 Product of the Year (huzzah!)," takes us patiently and steadily through a basic concept involving operational amplifiers, or amps-on-a-chip, explaining how feedback is heavily used in many modern op-amps to broaden what, in some cases, is a staggeringly low bandwidth to begin with. Don't worry - if Duncan can understand this by the end of the show, so can you.

It's beginning to look a lot like winter (finally), the chestnuts- er, questions are piling up, and the guys thought it would be fun to try to answer them all. In this episode, questions about capacitor burn-in, DIY projects, tube noise, outriggers and more are answered, and the album of the week is not one, but TWO lovely albums which share a lot in common. They come by different origin -- from Great Britain and France -- each with their own unique vibe, and somehow they sound great together.

In this episode, hosts Darren and Duncan discuss preamplifiers, starting with the "why" and continuing through the "what" and "how". Some preamplifier makers out there are aiming for a neutral sound... but is that really what we want in a preamplifier? Darren's opinion on this as one of the possible roles of the box in the middle of a system chain might surprise some. This week's album recommendation features an amazingly out-of-the-box young cello player and his debut album from a few years back.

The HiFi podcast audience is in for a treat this week, as the guys sit down with their friend and mentor, Paul McGowan, for a wide-ranging discussion about HiFi audio and other things. Paul shares what's going on lately with his recording project, jumps in with the guys to answer a listener question about black backgrounds, and offers a look back at some periods of time in audio's recent past when things were really happening. The album of the week is the second one we've picked from famed drummer and composer Tony Allen, and everyone is going to have to be OK with that because this album is unbelievably lights out good.  This podcast is powered by CommonGround Cables Whisper power cable.

We all started somewhere with this hobby, and we were all beginners at one point. But compare being a beginner now, after decades of the growth of the internet, to learning about the audiophile hobby in the 70s, 80s or 90s. There is almost too much information available now, and too many choices and paths to take. It's no wonder that some beginner audiophiles struggle to figure out where to start. In this podcast episode, the hosts go through their steps for the beginner and highlight where he or she might begin their personal audio hobby.  This podcast is powered by CommonGround Cables Whisper power cable.

In this episode of The Hifi Podcast, the guys deliver a more focused and nuanced set of guidelines for evaluating gear, whether it be components, speakers or cables. The topic comes up on the podcast again and again, because it's the literal backbone of the audiophile hobby. The ability to listen and perceive subtle differences is so important, and it becomes easier over time, after lots of exposure. Following these rules will ensure the listener maximizes the evaluation process, truly getting to "know" a piece of equipment through and through.  This podcast is powered by CommonGround Cables Whisper power cable.

This week, a listener question once again prompts the podcast topic, and while the guys don't exactly agree with the premise, its a great excuse to talk about the subject matter: How to optimize and get the best from a low-cost audio system. Questions about intermodulation and power round out the early segment, and this week's album pick features one of the best instrumental recordings the guys have heard in a long time.  This podcast is powered by CommonGround Cables Whisper power cable.

In a recent episode, hosts Darren and Duncan talked about a system's ability to collect and drain RF interference through the connected enclosures and low-impedance paths to ground. In this show, the guys -- and Darren specifically -- drill down further into high frequency bogey man land. Are modern chassis boxes even good at being faraday cages? How do designers maximize effectiveness in removing RF from a circuit, and what about tubes? Lots of questions answered in this fairly geeky episode of The Hifi Podcast.

This episode gets a great start thanks to so much goin on in Darren's two systems at home, including the reintroduction and repainting of the Dunlavy IVa system, cables burning in and the planned LPS addition to his reclocker. Also, his parents are in town, which means there are now distinctly fewer electrical components to trip over on the ground. 

Questions about the Matrix X-SPDIF 2, hexagonal listening rooms and more are answered, and the fellas are saved by a listener with a solid explanation of how to pronounce the French tube amp maker Jadis. (It's zha-dees)

When it comes to polarizing debates in hifi audio, none is more common than the subjectivist versus the objectivist. As the guys tackle this well known topic, it becomes clear there is appreciation for both sides. Both have some decent points and also some failings. The guys share personal experiences and try to find some humor in the sometimes exasperating debate.

Have you noticed the absolute proliferation of cool digital audio products in the sub-$500 market lately? With so much buzz around new class D modules and affordable R2R DACs and even budget speakers that are "specs monsters", the hosts of The Hifi Podcast believe now is the best time to be a budget audiophile.

There are some interesting quirks in some of the eye-poppingly cheap gear from China, with occasional designs focused solely on being impressive in one area or specification. Still, the sheer volume and variety of enjoyable and reasonably-priced products coming from the world's most populous country is energizing, and a complete boon for the growth of our zany hobby.

Earlier in the episode, the guys find it difficult to stay "on segment", with a diversion into the self noise of resistors and a discussion about objectivism and subjectivism in hifi audio. A listener question about power cables brings the boys back to reality.

This week's album recommendation is surprising. Debut albums shouldn't sound this good, and this one from an up and coming UK artist is musically fascinating to boot.

In this episode, a listener requests a deeper dive into room treatment for optimizing sound in a HiFi listening space, and the fellas oblige. In fact, Darren and Duncan leap at the chance to talk about the curious look of some commercial treatment products, bemoan the high prices of some seemingly cheap-to-develop elements, and generally touch on many important elements of the entire equation. The Album of The Week this time hits a different genre than usual, with a record from one of the top modern choral groups recording today.  This podcast is powered by CommonGround Cables Whisper power cable.

No speaker DIYer likes to read  a paper about the effects of edge diffraction on speaker baffles AFTER cutting out the driver holes. An inch left or right, and that tweeter could have sounded much better. 

No DIY amplifier builder wants to miss out on that important forum post where a fellow DIYer discovers an error in a schematic.

DIY audio projects  can provide immense listening satisfaction to the adventurous audiophiles who attempt them, but sometimes, challenge and trouble can hide around every corner. In this episode, the guys share some important things they've learned along the way in their own DIY projects. 

Cables, amps, speakers or digital are in focus, with some added attention to the art of soldering. This week's album recommendation has been in Duncan's library for a year, and is finally getting its due time in the spotlight.

"Not all distortion is horrible" is a notion many come to observe at some point along the audiophile journey. Maybe that's not the best way to put it. How about,  "some distortions are less horrible than others".

In past episodes of The Hifi Podcast, Darren and Duncan have talked about complex versus simple distortions, and the fact that simple circuits and simple devices distort simply. And simple distortion is much, much more tolerable to our ears.

Intermodulation distortion (IMD) is a complex beast of a distortion, creating byproducts of the difference between competing frequencies. A shimmering cymbal hit with fundamentals of 9KHz and 9.1KHz for example will produce an IMD product of 100Hz. Yes, that's right - artificial bass noise created from within the amplifier, for just these two tones. Imagine what happens with real music playing!

This week's episode focuses on IMD and explains why amps are the biggest culprits of this sonic bugaboo.

Also in this episode, the guys answer a couple questions about system battery power and round listening rooms. The album of the week is a killer sounding new joint from perhaps the biggest name in bluegrass right now.

The owner of a very popular U.S. hifi audio cable maker calls hifi audio "a drug." And he's not wrong at all. Think of the yearning to listen after periods of being away from our systems. Think of the teleportation to a different place when everything's clicking. Think of the times we had to bargain, beg and borrow to upgrade to the next best thing. And on that topic, think about how we chase the audio dragon and are always interested in "better," or at least "different."

Hifi is a drug, and in this episode, after listener questions are answered and the guys check in on each others' audio projects, they come to grips with the notion.  As they see it, there are worse addictions and worse drugs -- metaphoric or actual. But it's always good to pull on the ol' honesty glasses from time to time.

This week's album comes by way of an unknown drummer but features a very well known guitarist.  The story goes, during their three-night run in Memphis they recorded everything. And the recording quality is staggeringly good.

They also all three developed food poisoning. After the show, they all felt horrible about how they felt they played that they shelved the project. Listen to the final segment of the podcast to hear what happened next.

But. Did the fellas pull it off is the real question. Were hosts Darren and Duncan able to recommend yet another Charlie Hunter album without being noticed?

When it comes to wave frequencies, sound waves we can hear live near the absolute bottom of any spectrum you wish to peruse. Sound waves are not electromagnetic or radio waves, but to an RF engineer they might as well be “DC.”

And sound waves, though different, can in one way or another be affected by these other guys. Radio frequency and electromagnetic waves can influence the electronics we use as source gear or amplifiers, thereby changing the sound waves we hear.

None of this is news, especially to audio designers. But in this week’s podcast, hosts Darren and Duncan dive into the topic of shielding, explaining how modern audio designers deal with EMI and RF, and covering the act of draining and grounding from a overall system perspective.

This week’s album is but a single, but oh, what a single it is. Coming from Poland, young guitar prodigy Marcin serves up his take on Beethoven’s classic Moonlight Sonata.

For podcast hosts Darren and Duncan, the hifi audio expo Rocky Mountain Audio Festival was more than their "hometown show."  Years before the two worked in the industry, the show represented a connection to the whole world of audio, accessible through a portal just down the road. It was as close to audiophile teleportation as it got for the guys.

In more recent years, it took on a new feeling as the two began to represent their companies and transition to the other side of the audio show affair. And after years of stressed-out system setups in hotel rooms and back-breaking schlepping of gear up and down freight elevators, it has still never gotten old.

Darren and Duncan are personally crushed to see their favorite hifi audio event be put to rest, so in this episode they talk about the news and go through some great memories from RMAF past. And they spend a good amount of time explaining what has been so special about the event and how it has managed to improve over the 10 years since its founder's unexpected death.

This week's album rec is a surprising debut album from a young lady whose voice will stop you in your tracks. A lady called Lady Blackbird and an album called Black Acid Soul.

As a listener,  being restricted by a budget is a form of not getting your lunch for free. A designer might look at a single objective as the highest priority -- and then have to perform all kinds of feats to make that happen. A musician may want more sub bass on a mix than is prudent.

And on, and on. There are so many examples of places in audio where clever ideas simply can't compete against the laws of physics.

In this episode of The Hifi Podcast, the guys and their regular guest host Chris Brunhaver talk about the many sides of this truism of audio.

In the questions segment of the podcast, Chris explains all about "power response," and the guys discuss the pros and cons of upsampling.

This week's album, Sideways EP by CLN, is some really cool electronic music that experiments with organic sounds and presentations.

When bringing a vintage piece back to its original glory, whether as a DIY project or with the help of a professional, you have to decide if the restoration is going to attempt to use vintage parts from the same era (if that's even a possibility), or whether newer and better components should be used.

This is more of a temptation with speakers, as material science advancements have wrought incredible performance increases over the years. But it's also more challenging with speakers.

Speaker drivers can be so unique and quirky that entire speaker designs can revolve around minimizing the unique issues that arise. So the act of updating a speaker means you'd really want to understand the speaker fully, from drivers to crossover components, and in the end an update may not be possible without a total crossover overhaul, threatening to entirely change everything that made the speaker worth restoring to begin with.

This is some of the thought process behind Hifi Podcast hosts Darren and Duncan's plans to modify their Dunlavy speakers. Armed with a decent understanding of the crossover and a growing understanding of the drivers, the guys take this episode to talk about epiphanies learned and consider possible next steps.

Neither of their sets of Dunlavys are broken, per se, although Darren's does need a new tweeter. But that's a simple fix -- the more tempting option could involve beryllium or textreme. Tune in to find out where the projects are headed.

This week's listener questions are about bass traps and  the above DIY projects, and the album of the week, Afrobeat Revolution by Tony Allen gets an enthusiastic recommendation.

In this episode, the guys talk about harmonic distortion and the difference in sound between a steel beam hitting a concrete floor and a stack of bamboo hitting the same floor.

What does a cheaper Class D amplifier have in common with the steel beam? What is negative second order harmonic? And what's so interesting about square waves for measuring amplifiers, when music is made of sines?

These questions and more are answered as hosts Darren and Duncan discuss the nature of harmonics, and how different distortion characteristics affect human ears.

Great questions from listeners discuss how to choose the right phono cartridge, and how to find humor in audio. The album of the week, Dreamlike by Electric Kif, rounds out the show.

When hifi speaker makers offer more than one "flavor" of speaker, it's typically to satisfy both audiophiles who seek more resolution, and those who want a more "fun" speaker. This is a wise move, as neither camp is likely to be swayed by a middle-of-the-road compromise.

One of the joys about the audiophile hobby is that you don't have to compromise your desired path. What sounds good to you IS good for you. It's because of this that we see so many approaches to the same objective in hifi audio.

This freedom and variety means that many people are chasing many different sounds. And when it comes to the topic of system resolution, this is an area where we see people differ more than others.

"Resolution is a double-edged sword" means that with it, you can reach new heights. But you're also presented new challenges. In this episode of The Hifi Podcast, the guys talk about what resolution means, and how to find your resolution "sweet spot."

Just for fun, this episode was done in backwards show order. Enjoy.

This week's episode is spurred from a listener question about how The Hifi Podcast hosts Duncan and Darren actually go about shooting out different pieces of gear in a reference system. Some say you should move quickly between A and B to avoid getting caught in biases and to stay within the "auditory memory window"; others suggest taking things slowly and letting subtle differences build up in your mind with time.

Well, you must be new to hifi audio if you don't know that there are a ton of ways to do everything  while still reaching a similar result. The same goes for this, although the guys certainly do have their preferred methods. Listen in as they talk about checklists, memory, mental peace and more in this wide ranging discussion about listening.

Also in this episode, a listener question about a career path in audio design is answered, and the album of the week features a musical act that toes the line between audiophile gadget music and melodically sweet and memorable art that anyone would love.

Welcome to the new season and new format for The HiFi Podcast. This time, the boys are back and apparently recording under a popular confluence of flight paths, but if you can get past the air traffic noise, this episode is one you don't want to miss. Darren dives deep into the makeup and uses and pros and cons of Gallium-Nitride Field Effect Transistors, or GaN FETs. This is thanks to a listener question, and if you would like to prompt a podcast topic, be sure to contact us via our website. This episode's Album of the Week recommendation is an intimate date with a very creative and nuanced artist named Mitski.  This podcast is powered by CommonGround Cables Whisper power cable.

Harmonizers. Resonators. Grounding boxes filled with dirt. Green dots, quantum tunneling, past-time-disentanglement, beeswax, tellerium,  C37 lacquer, nano liquid... the list goes on and on. What some folks in the hobby consider heretical snake oil, others have tried and found some degree of success in their audio journeys.

But where is the line? Perhaps the "madness line" is different for each person, and since this is supposed to be a fun hobby, perhaps there is no line that needs to be drawn.

Regardless, in this episode of The Hifi Podcast, the guys discuss where their line lies on the scale of interesting or "out there" audio approaches.

This week's questions segment is a good one, including a tip from a listener to help another podcast listener who had a question last week. And interesting idea for a cue lever delay is in there, as well as talk about step up transformers and hysteresis distortion.

This week's album is a killer acoustic record that has been a staple of Darren's system for many years. A quintessential American folk singer in a recording that drips with feeling and life. Tune in to find out who and what.

It begins with a flip of a switch, and often on the first power-up of a new component. What's supposed to be one of the most fun parts of the experience descends quickly into horror when the dreaded HUMM comes through the speakers.

Most of us have heard this horrible noise before, but it isn't always clear what the cause is, exactly. In this episode, engineer Darren takes us down to the ground as we try to understand voltages, currents and potential differences on our ground lines.

This week's album recommendation takes us into the electronic music world, with an album full of remixes of a fun 3-track EP released late last year.

Being the right distance away from your speakers, and in a position in the room that minimizes room influence is a large part of the effort of creating audiophile sound. This is mostly what you hear when the topic of the sweet spot comes up.

But today, the guys focus on  the physical makeup of that area, and how it affects the sound.

How comfortable are you? What's directly behind your ears? How high are you sitting? What's the mood like, and where are the distractions?

These questions and more are discussed  in this episode's focus on the sweet spot. Earlier on, two listener questions about DAC and streamer setup tips and tweaks are answered in typical comprehensive fashion, and this week's album of the week makes the guys try their best not to snicker as they describe one of the best-recorded digital albums this year.
