Linn’s founder, Ivor Tiefenbrun, wanted to sell turntables. He did this in the early 1970s by building a great product, certainly. But more than just a product, he threw a bit of wisdom into the high end lexicon that I believe has had more of an impact than anything else I can think of. The […]

When we set our sights far in the future the world looks nice and rosy. Imagine that new pair of speakers gracing your living room, the new amplifier, the rebuilt room. According to Mark Twain imagining the future takes a combination of things. “Kindness is the language which the deaf can hear and the blind […]
Paul McGowan writes … In my mind, there’s no question that between components the best connection is balanced. Balanced cables offer lower noise and better sound. I understand there are single-ended holdouts (wait, we disagree on something in audio?). Perhaps their equipment doesn’t support balanced. Perhaps their cable collection doesn’t include balanced. Or maybe they […]
Speaker stands are great for getting the height of small 2-way and bookshelf speakers just right but they can have the disadvantage of being resonant. What’s the best way to damp them? Watch Now
Paul McGowan writes: The summer of 1977 found my partner Stan and I looking to increase our sales of phono stages and we thought we would try and entice a few dealers to carry the product. Up until this day we were 100% direct-to-customer, something you see more of today in high-end audio, but back […]
In a recent 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 faithfully reproduce a larger version of the input signal on their outputs. In our example yesterday we placed […]
Paul McGowan … If we’re playing a dynamic piece of music at a moderate level it’s likely we’ll not hear the soft parts of the score. A little compression would enable us to hear both the softest and loudest passages. Yet to purists, compression is about as acceptable as farting in a crowded room. Let […]
Many receivers can accept SACD DSD files over HDMI but why can’t high-performance DACs? Are there any that do and if a low-cost mass-market receiver can play DSD files from SACD why not a high-end product like from PS Audio? WATCH NOW
Computers delivering music to DACs sound different. Some are better, many are worse, some downright awful. So if bits are bits, how can this be true? Is there a good USB solution to feed a DAC? Watch Now
Paul McGowan: If you’re serious about building a high-performance audio system you have to pay attention to the AC power. It’s a constant theme with me because power is the foundation of our systems. There aren’t many great structures standing on weak foundations. Power Plants solve many problems but they need a head start. One […]
If you’re on a budget what’s the right place to put your money? Do you spend the most on sources and electronics or loudspeakers? Electronic manufacturer Paul offers his opinion to you. Watch Now
In our search for sonic truth, there comes a point where the systems get so good their “truth” is more about our personal preference. In fact, personal preferences often trump truth. We know we’ve gotten closer to the truth when it matches what we believe to be the musical truth. Of course, no one knows what musical truth is. […]
I remember the first time I became aware of what we call Listener Fatigue. It was many years ago when there was only turntables, vinyl and most people listened to nothing but tube electronics; solid state was just coming onto the hi fi scene and we are part of that pioneering effort. I know I’ve […]
Most tube power amps have an advantage over most solid state amps: high voltage. If we look at a typical tube vs. solid state design, that tube design might have up to ten times more voltage than the solid state design – at least in a preamplifier. The tubes need the high voltage to operate […]
This’ll be the first of a few posts where we delve into networking and computer audio systems. In prior posts we looked at what I would refer to as a closed system: a single computer with a DAC attached to it. This works fine but has a number of drawbacks, many of which are not […]
Paul McGowan writes … There sure is a lot of confusion over sample rates. We hear about CD-quality sample rates at 44.1kHz (and its multiples), or another common sample rate, 48kHz (and its multiples), and then there are multiple higher sample rates (176kHz, 192kHz as examples) and of course DSD. Lots of numbers. All very […]
Paul McGowan: One of the more satisfying affirmations happens when two or more unrelated people make the same sonic observation. We send out an update and emailed observations roll in. “What happened to the bottom end?” Or, “The top end just opened up.” For better or for worse, it is fascinating that so many unrelated […]
How does one measure the differences between amplifiers when they clearly sound different? The first and simplest measurements are frequency response and noise levels: frequency response shows us that everything we put in makes it through to the output and noise levels are an obvious thing to measure so we don’t have hiss. Fancier measurements […]
It seems like a simple potentiometer in a box would be the cleanest and best sounding preamplifier on the planet. So why aren’t they more popular and what’s PS Audio doing about them? Watch Now
Paul McGowan writes: When I sit in the sound room for critical listening of course I always grab the “hot seat” because certainly in my system, that’s the place where the best imaging and tonal balance take place – and not just by a little bit – it’s seriously better than any other seat in […]
What is the significance of the folding transmission line in a loudspeaker? My guess is that not many of you have heard of a folding transmission line in a loudspeaker, much less ever heard one working. The late Bud Fried, from Fried Audio (pronounced “freed” as opposed to what one might do with eggs), was […]
Paul McGowan … TAS reviewer Michael Fremer has an extraordinary music system—the best vinyl setup I’ve ever heard. And it makes sense that he does. Mike’s spent a lifetime learning about vinyl audio reproduction and hand selected the best equipment in the world. His digital setup played through that same setup doesn’t quite match my […]
