It may sound funny, the headline of this post. I love the sound of tubes, have owned tons of tube equipment and yet – I have never designed a tube piece ever. And add to that [...]
How boring if you’re biased right in the middle eh? You don’t lean to the left or the right, you’re just middle of the road for everything – as if you don’t actually have an opinion. [...]
If you’ve managed to wade through this series of posts on tubes vs. transistors you’d know that while there are indeed fundamental differences between tubes and transistors that by themselves have a major impact on the [...]
No doubt you’ve heard terms like class A, push pull, , SET, full complimentary, single ended etc. These terms all refer to how we use an amplification device rather than the amplification device itself (like a tube [...]
This post will most likely stand the hair up on the back of EE necks because it’ll be riddled with inaccuracies I will use to make a point about why devices sound differently in audio circuits. [...]
In yesterday’s post we covered the fundamental differences between tubes and transistors and one of those we’re interested in is linearity. Tubes and transistors are only partially linear devices – which means they will not always [...]
In yesterday’s post we covered how the mysterious crystals used to make radio receivers first were spun off to the vacuum tube and later rediscovered to become transistors. Today let’s cover some of the fundamental differences [...]
In yesterday’s post covering the invention of the vacuum tube and its principals of operation we learned that small crystals were used as the basis for radio receivers and that inventor Lee De Forest came up [...]
This is the first post in our series on Tubes vs. Transistors. I’ll do my best to keep this fun, informative, not uber technical and to the point so we can all have something to look [...]
Now there’s a hot subject for you, one that’s been debated for as many years as the two have coexisted in the world of high-end audio. First let me suggest that there can be no debate [...]
Good friend Bill Low, CEO of Audioquest Cables, sent me a note answering the question about purity and perfection in audio. “The answer seems obvious … Do No Harm … meaning that the inevitable compromises required [...]
Synchronous and asynchronous are two buzz words manufacturers realize gets people’s attention. We may not understand what they mean but we’ve figured out asynchronous is better than being synchronous. So a new class of DAC has [...]
Have you ever noticed that many dogs resemble their owners? I think the same is true for equipment and the personality of the designs. In our hand-crafted industry of the high-end many designs bear the sonic [...]
The language an artist uses to describe her work is by necessity vague and intentionally non-specific. How else could she describe the feeling of the work? The language a programmer uses to describe her work is [...]
In the late 1960′s the way music was played over the airwaves was going through a major shift, much like it is today. For many years only songs of less than about 4 minutes were ever [...]
In the early 70′s Stan (The “S” in PS) and I only made phono preamplifiers. They had no controls, just a turntable input and a set of RCA outputs. Designed to go into the auxiliary inputs [...]
“The justification for a great music system is the same as for a great instrument: It makes possible a musical experience that cannot be duplicated by lesser means” My friend Jim McCullough who owns the Cello [...]
Yahoo is suing Facebook for violating some of its patents for technologies it both uses and doesn’t use. Yahoo waited years to take this action and it wasn’t until Facebook announced its IPO that they went [...]
Ever notice how something is obvious only after someone points it out to you? In our post on Software Jitter I got several emails from folks telling me “that’s an obvious distortion path”. True enough but [...]
Dave Paananen, our director of engineering, asked “Isn’t it obvious the need for an album or CD is rapidly becoming unnecessary?” At first I dismissed the thought, so ingrained is the notion of an artist creating [...]
Just when we thought we had it all figured out along comes a new form of distortion to tackle: software jitter. The culprit here is, unfortunately, a very necessary component in the chain of digital audio [...]
Alan Sircom, writing in the April issue of Hi Fi Plus magazine, suggests that the problem with getting newcomers into the high-end is they already find their means of reproducing music “good enough” – so why [...]
We wanted to be able to explain how a Power Plant regenerator works in less than 3 minutes to people who had zero technical knowledge. I didn’t want an ad or a fluff piece, but something [...]
In 1973 when we first started PS Audio everything mattered to the sound quality path: types of capacitors, types of transistors, resistors, circuit topology, connectors, power supplies, chassis builds and so on. Then we moved to [...]
Fundamentally change the form factor of their mobile devices from backlit LCD to see-through OLED. How do I know that? Because it’s the obvious thing to do to solve a basic irritation. Let me give you [...]
There are just too many. I have lots of them especially when it comes to new products and new directions for our industry – and I am sure many of you reading this post have them [...]
In response to our little series on purity and musical truth one of our Australian readers posted this comment: “It’s all about enjoyment. I have listened to a number of systems that are very detailed and [...]
Several of you have written me suggesting the issue we’ve been discussing on purity has more to do with the playback equipment than the way it was recorded. I think it’s more complicated than that. There [...]
I am convinced Bob Carver is a crazy genius. He’s given more to our industry than most and always surprises and delights with his innovative approach. His tiny cube amplifier, his miniature room shaking subwoofers and [...]
In yesterday’s post Are vinyl records filters I think we struck a nerve. In that post I pointed out that many of us find vinyl records to sound more musical than a digital recording – yet most [...]
Have you ever pondered the fact that many new vinyl releases today actually are recorded, mixed and mastered digitally before being transferred to vinyl? Because many studios today are digital based it’s easier for musicians to [...]
As spring hits and summers is nearing hi fi manufacturers and dealers have to start figuring out how they will make it though the long hot summer of the hi fi season. Sales of hi fi [...]
Most high-end audio systems are very personal because they are hand assembled by the owner. Rarely are any two alike and that’s kind of what makes this sport fun. But if dealers sold pre-assembled “cookie cutter” [...]
In yesterday’s post Separating the wheat from the chaff, I mentioned that the retailer is the perfect sorting house – choosing and selling only those products that perfectly reflect the dealer’s brand promise and makes it [...]
For those non-farmers out there (like me) the wheat is the good part and the chaff is the throw away not worthy of eating. So if we were ever to set up some certification standards for [...]
…that is the question from a great article just published on our magazine PS Tracks. Lawrence Schenbeck, our resident musicologist and fellow Audiophile, writes a wonderful thought piece about Blu Ray opening up the possibility of [...]
On the PS Community Forums we’ve been discussing a new product to serve music and how that product gained some features that not everyone agrees with: specifically a headphone amplifier. The question asked is “why should [...]
We’ve been focusing on the importance of the room to a stereo system over the past couple of days. Let’s dive a little deeper. Nelson Pass designed an interesting product called the Shadow a while ago. [...]
Yesterday’s post about rooms and loudspeakers sparked a lot of questions about what diffusors to use and how to place them. Funny thing is, there’s really no good answer any more. I used to advocate RPG diffusors [...]
Good speakers in a bad room won’t sound as good as bad speakers in a good room. Sorry, I know that’s perhaps not something you want to read. We spend a lot of time and money [...]
A great writer once said in a note to his friend: “I apologize for the long letter. I didn’t have time to write you a shorter one.” That note was from someone who commented on the [...]
Free advice is worth exactly what you paid for it: nothing. But is that true? If I recommend a technique to help your high-end system sound better and it works for you, what was that worth? [...]
There are not many subwoofers out there that have servos running them and that’s a shame. A servo is like a little microphone placed right on the woofer that listens to what the woofer is doing, [...]
I get a lot of SPAM in my inbox. When I go to unsubscribe I sometimes get a notice that my request will be processed in 24 to 48 hours. This implies there is some human [...]
Yesterday’s post Perfectly Legal had a few of you scratching your heads about being law breakers. If you rip a CD and then sell it or give it away, technically you should delete the stored copy as [...]
If you own a CD it is perfectly legal to sell that CD. It’s your property. It is also perfectly legal for you to make a copy of that CD for your own use on your [...]
Hard to imagine that a piece of plastic has a personality but if you play vinyl records, each is an individual separate and distinct from all others. Vinyl personalities depend on the pressing, the number of [...]
I was on the phone with our marketing company Creativello in Seattle and trying to explain what it’s like to be an Audiophile: what moves us, what motivates us, what really floats our boats. When I got [...]
Back in “the day” a manufacturer would launch a new product to waiting Audiophiles and the first reviews of it would generally start to emerge perhaps 6 months later. In the meantime, many units were sold [...]
When someone presents an idea it’s really easy to reject that idea and cite examples of why it won’t work. It’s really hard to do the opposite. One’s easy, the other requires work because to be [...]
Much of the feedback on this subject centered around the name “high-end” and the general feeling the name’s a turn off because it equates to “high-priced” in people’s minds and doesn’t really describe the concept. I [...]
Once we have all the elements to grow the high-end community in place: brand, certification and access then we need to get the word out and watch it grow. This process may be best suited by [...]
I’ve posted about this before: there simply aren’t any good places to go to find pre-packaged entry or mid level high-end audio products. That’s a mistake. If we’ve gone to all the trouble to create a [...]
Step 2 in building a growing high-end audio community is to identify, qualify and certify a group of products giving people permission to purchase. In the first step we created a simple understandable brand around high-end audio [...]
The high-end doesn’t really have a brand or a neat way to bundle up its concept and present the package to someone interested. That’s a problem. For the process of engaging a new community of high-end [...]
Since no one else in the high-end seems to have a clue of how to bring in new people, let me suggest a path towards success in this venture and perhaps someone reading this will have [...]
Audiophiles have a small close knit community. Why would we care if it gets smaller or bigger? Because small means fewer options for equipment, new technology and better recordings that brings us closer to the music [...]
Yesterday we asked the question: why aren’t more new people getting involved with the high-end? I rejected a popular notion that the youth of today are different and do not seek quality. Today let’s remember how [...]
If you read any of the magazines or blogs in our industry you’re probably aware that the high-end isn’t attracting a lot of newbies to the field. Why is that? I read a lot of opinions [...]
Yesterday’s post was long and several of you asked if I couldn’t make one shorter. [...]
In my post Getting what you bargained for I talked about the rise of the second tier dealers who offer low prices instead of what the neighborhood retailer provided and how that’s changed the face of [...]
I’ve been noodling on a comment made a few weeks ago that high-end audio is mostly a status symbol owned by wealthy people who do not care about audio or music. I must say I find [...]
In yesterday’s post we we lamented the shift away from the neighborhood dealer who provided our advice, information, opinions and service. There are a number of reasons why this has taken place and one we’ve not [...]
In our comments section of PS Tracks magazine I mentioned how we in the high-end got what we bargained for when we chose the lowest price over service and advice. I thought it would make a good [...]
Yesterday’s post Good enough raised the hair on a few people’s necks wondering why I had apparently thrown in the towel and accepted having to make products and services that were just good enough. I must [...]
When is something good enough? I think the answer is complicated but if we boil it down to two simple measurements it becomes easier to answer: perfection level and expectation level. The perfection level measurement is, [...]
We just released some new software that changed the sound of our PerfectWave DAC. As is normal there’s debate on whether or not those changes are better or worse. For me there’s no question they are [...]
There’s increasing evidence that rhymes, poems, meter and cadence in stories were created not because they are beautiful but because they helped us keep the words straight before the advent of written language. It is how [...]
For the last two days we’ve been focusing on loudspeakers. We covered how they are anything but flat and why that’s not necessarily a bad thing – something good loudspeaker designers can use to their advantage [...]
Yesterday’s post about the gross inaccuracies of loudspeakers relative to the perfection of electronics raised the hair on a few people’s necks. So let me add to that. It isn’t clear that we even want our loudspeakers to [...]
Why is it we are forgiving and tend to overlook loudspeakers as a source of coloration in our systems yet demand perfection in our electronics down to the tiniest degree? We are convinced that tenths of [...]
I was chatting with one of our customers on a recent tour of our facilities and he asked if it would be overkill to strive for higher sampling rates and greater bit depth in recordings given [...]
Reader Barry McCarthy wrote me: “I like reading your quick daily thoughts on the state of our hobby. Today’s post caused me to to think of over abundance and how we live with it. I have [...]
I have always smiled when I witnessed fellow designers getting offended by some engineering claim they either disagree with or can’t understand – that is until it happened to me. Recently our engineering team has been [...]
Several readers commented on yesterday’s post about adding features to our free music management program eLyric. The question asked is “why free”? It’s a good question and one that deserves an honest open answer. eLyric was [...]
One of the challenges facing any designer is how many features to add – or put another way – how many features not to add. The general thought is the more features a product has the [...]
I have been reading novels on my Kindle as of late: my son won’t consider it because he doesn’t want to give up the tactile feel of a book. On the other hand, I can’t enjoy [...]
I love brilliant inventions – especially the ones that are super simple yet perfectly designed – rare as they are. A GFI is one such invention. You know, the AC plug near your bathroom sink with [...]
I have been to homes and shows where I was asked to listen to some really bad loudspeakers – kit that is so far away from accurate that it’s laughable. And yet I can still hear [...]
Mark Lewis our resident Brit working in our sales department and helping me with the Reference system installed a pair of Anthony Gallo Strada loudspeakers for me to hear – having never heard a pair. He’s [...]
Driving into work the other day I noted a sign that read “lose 15 pounds in 30 days without diet or exercise, guaranteed.” A magic bullet! Clearly this won’t work for me or anyone else and [...]
Opening my email I noticed a audio retailer was having a sale and it was tied to a calendar occurrence. Is it just me or do you think it’s strange retailers feel the need to tie [...]
In yesterday’s post about my dislike for Sample Rate Converters I must add one more thought: all sample rate converters are not equal. Some actually help the sound while most do the opposite. This is important [...]
There’s a quiet conspiracy afoot and something you should be aware of. The conspiracy is one of “don’t ask don’t tell” from DAC manufacturers. PS Audio is just as guilty as the rest. The issue is [...]
A couple of days ago I mentioned one of the emerging trends I am seeing is the desire of people to have someone else build their systems for them so they don’t have to do the [...]
In yesterday’s post I mentioned the trend of Audiophiles wanting complete packages delivered to their doors that provide a wonderful listening experience. A pre-packaged approach. I was imagining just the opposite this morning. How cool would [...]
In my travels I am seeing a shift from “hi-fi assemblers and tweaks” to the “gimme it all finished” mentality. In the not too distant past the trend was for Audiophiles to read the reviews, discuss [...]
I’ve written recently about increasing the rewards of creators who add value to something and reducing the amount of those that bring the value to the table yet create nothing. With that thought in mind I [...]
Every time I install a new version of our free music management software, eLyric, I am asked to agree to the EULA before I can use it. It’s annoying and I never read it. In fact, [...]
You probably read that Steve Jobs of Apple listened mostly to vinyl instead of his fabled iPod creation. He was a real music lover and preferred the sound of vinyl to that of digital. What you [...]
I have written a lot as of late about the issue of musicians and how they get rewarded for their work. It has ruffled a few feathers and I think that’s good. To be clear, I [...]
One of Paul’s Posts readers, Mark S, asks the question of why we manufacturers seem to work so hard at building kit that serves all music and all tastes equally well. I think it’s a good [...]
Why do we innovate? Because innovating means jumping feet first into the new and that leads to being a craftsman of our future. [...]
Do you think the gas meter on your car lies? You know the one – it tells you there are 10 miles to empty. I am guessing it’s “conservative” which is a kind way to say inaccurate. [...]
We’ve discussed plenty of controversy about how musicians and artists will get funded in this day and age of the internet. I haven’t any magic to offer but when I do see a small ray of [...]
One of the cleverest solutions to amplifier designs came to our attention through our old friend Nelson Pass, then of Threshold. We always referred to it as the “sliding class A bias circuit” and what was [...]
Remember the Monty Python skit of the fat guy exploding after eating one more thin mint? When it comes to music, do we ever have enough? When I look at my shelves full of physical media [...]
The sorting order of a major music library is critical as I have written about as of late – composers by their last name, artists, orchestras and bands by the first/last names. Once you get the [...]
As I have been immersed in building my big library I have noticed something interesting. In classical music you sort your library by the name of the composer – Mozart, Beethoven, Dvorak and in pretty much [...]
In yesterday’s post Dedicated Hardware we talked about the beauty of buying a product dedicated to a specific task – simply because it is designed to do one thing – and do it well. Such a [...]
A bias right in the middle
True - which is ne of the reasons we use complimentary symmetry design
A bias right in the middle
But in a sense in your single ended example there is no real middle. I

So that others can find it on the internet, read it for themselves and
