PS AUDIO: What and how

In any endeavor, it’s important to be clear about what you hope to achieve and then worry about how you will get there. Here’s a good example from two recent recording sessions at Octave Records. Both sessions used the Steinway piano in Octave’s tracking room. The first was a solo classical music piece while the second was a group pop track. Does […]

I WAS PISSED. Learning that code and all the formulas I hadn’t yet stuffed into my head would make no difference in my ability to understand the inner workings of circuitry.

50 years ago in the dark ages of my past, I was determined to learn how circuits worked and what made amplifiers tick. Working full time as a disc jockey for the US Army in Germany at that time I had no practical means of attending school. Enter Herr Rudy Stroebel, chief engineer of the […]

UNDERSTANDING: Impedance

PAUL MCGOWAN … For those with a clear understanding, this is a good post to skip. For those still unclear about what it means when we speak of high and low impedances, this might be right up your alley. The simplest way to think about impedance is to consider it an opposer. The higher the impedance […]

UNDERSTANDING: Op amps vs. chips

I wince when people equate op-amps with chips. An op-amp describes a topology, not a chip. Yes, the op-amp topology is often built onto a silicon wafer, but we should be careful not to forever bind the two together unless we’re clear about the difference. (If you’re technically minded there’s a great paper describing in […]

I am most comfortable in the company of engineers.

It’s more than just camaraderie. To non-engineering folk, our conversations might sound like a different language what with all the terminology bandied about. But more than terminology is the implied understanding of bigger concepts. Terms like -3dB, half power, slew rate, open loop, rise times, wave shapes, carry with them major implications. If our depth […]

A DC blocking capacitor is a heck of a lot simpler than a complex DC servo-eliminating circuit.

PAUL McGOWAN / PS AUDIO Conventional wisdom would have us believe best results are obtained via simple solutions. The simpler the solution the better and cleaner the outcome. I find simple solutions are often the most difficult to accept and inevitably the hardest to find. How many times have you gone round and round in […]

DIGITAL: The thing about digital volume controls is …..

Paul McGowan writes: I struggled with how to write this because the subject’s rather complicated and in the end decided to keep it simple.  Heck, it’s Sunday after all and we’re supposed to be taking a day off. Yesterday we covered analog volume controls and how they, by virtue of adding something into the signal […]

THE $35 RESISTOR: I am well aware people in our HiFi Family think were nuts. And, that’s ok. Better nuts than boring.

When people ask me if parts of identical value but different construction sound unlike one another I kind of scratch my head. In my world, parts in the signal path all sound different. It’s like asking me if chocolate and vanilla taste different. The answer seems so obvious. But then I climb out of my […]

MIDBASS: How to get it right?

PAUL McGOWAN AGB’s latest column has been uploaded and for those of you interested to see what the Audio Hitman has to say about EQ’ing your system and frequency response in general, go here to read the article.  For the faint of heart, I recommend abstaining. As I worked through the setup of the IRS […]

HARD WIRED: At first thought, it would seem obvious that a hard-wired connection between a digital source and a DAC would have to be better than a wireless connection where multiple steps and technologies combine to do the same, simple transfer of data as a simple hard wire.

At first thought, it would seem obvious that a hard-wired connection between a digital source and a DAC would have to be better than a wireless connection where multiple steps and technologies combine to do the same, simple transfer of data as a simple hard wire. But because something is obvious doesn’t necessarily mean it’s […]

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 […]

UNDERSTANDING: Room calculations

PAUL McGOWAN Our rooms are as important as our equipment yet only a scarce few of us have the luxury of choosing our room dimensions. Typically we take what we can get within our home and make the best out of it. With our new building in process, we’re heavy into the architectural tasks of […]

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 […]

UNDERSTANDING: Line sources

PAUL McGOWAN 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 […]
