PS AUDIO: Then, something funny happened. I began to hear things others did not

When I first got interested in high-end audio in the prehistoric early 70s I was told I didn’t have an ear. I struggled to hear differences obvious to others and so I placed myself in a box with a label that read, “not a good listener”. Because I hadn’t an ear I relied upon those […]

MASTERING

Paul McGowan / PSA Audio After more years than I can count I am still trying to figure out mastering. This might seem kind of odd considering our own in-house mastering engineer, Gus Skinas, is one of the world’s most respected. Yet, still I struggle with defining exactly what they do. I do know they […]

Does purity lead to distortion?

There are many multi-driver speakers, but few that go floor to ceiling like the IRSV. Floor to ceiling multi-driver speakers are called a Line Source. What’s counter-intuitive about a line source is how specific the imaging can be. With that many drivers, one would think the image would be tall, rather than lifelike, when the […]

….. but if you ever have a chance to experience the effortlessness and pinpoint imaging of a true multi-driver line source, grab it.

When people come to hear the IRSV system in Music Room One they’re always in awe of the number of drivers: 36 tweeters, 12 midranges, 6 woofers per side. Most loudspeakers have one of each: tweeter, woofer, perhaps a midrange. On a speaker like the IRS, the duties are shared. Each tweeter handles 1/36th of […]

Line sources

Kevin in Wappinger Falls New York (wherever that is) asked me an interesting question recently. “Arnie Nudell popularized the line source loudspeaker design and many of his most revered speakers such as the Quantum Line Source, the IRS 1B, the IRS V, and the Genesis 1 (and apparently at least the two larger members of your […]

VINYL TRUTHS: The thing is, we tune and tailor our setups to match the limitations of our primary sources. This can lead to over-reaching proclamations that one medium is better than another when the truth is not that at all.

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 own. That also […]

PS AUDIO: The significance of the folding transmission line in a loudspeaker?

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 […]

ROLLING IT OFF:

Paul McGowan writes ….. Recently I explained the real problem in using a direct coupled product like a power amp or preamp is not the DC they produce, which is minimal at best, but how these products handle DC from OTHER products.  If the designer has built the classic “DC to light” amplifier,  you risk […]

Where’s the music supposed to be?

Visiting audio clubs, dealers, trade shows and people’s homes is illuminating to me. I am always learning. Recently I sat in front of a dealer’s high-end demo system and was amazed at how wrong the image was. The entire presentation of the music was between my seating position and the loudspeakers: a logical place for […]

IMPEDANCE: Mix and match impedance

Popular audiophile lore has it that a mismatch in impedance between the preamp and amplifier will result in bass loss. Yup. If the amp’s input impedance is too low weaker bass will be the result. That’s true in the same way it’s important to pump the car’s accelerator before starting it. In the days of […]

SILENCE: What is it about the sound of audiophile silence?

Yesterday’s post sparked a number of comments and observations and one that came to the forefront was the ability of the subwoofer to help with a sense of space – not just hitting lower bass notes.  We all recognize a sub’s ability to produce the lowest notes of a piano or organ, T-Rex stomping and […]

HEADROOM: The ins and outs of headroom

Recently we covered one of the advantages of the higher power supply voltages afforded by tube circuits: linearity.  Today we’ll jump into the second advantage of increased voltage, headroom in power amplifiers. Headroom is a funny thing.  If you take a SET amplifier of perhaps 18 watts and try and get 20 watts out of […]

NELSON PASS: He designed an interesting product called the Shadow a while ago.

It was an active bass correction device that made sense – because instead of correcting the output of the speakers for bass problems in the room – it fixed the room itself and left the main speakers alone.  Not sure whatever happend to it but it mirrors an idea I’ve had for years: fixing the […]
