THIS IS FOREIGN TO ME. I listen to podcasts daily and find them a wonderful way of absorbing new information on the subjects that interest me. Here are some of my favorites:

Paul McGowan / PS AUDIO While emailing back and forth with several new members of PS Audio’s HiFi Family it became apparent they weren’t aware of our podcast, Ohm’s Law. In fact, turns out they had yet to everlisten to a podcast of any kind. This is foreign to me. I listen to podcasts daily and find […]

BIAS FEEDING: Ever notice how the more you become convinced of something the more you feed that belief?

Paul McGowan / PS AUDIO If we believe analog is superior to digital or vice versa, we tend to gravitate toward other groups that believe the same thing. It seems true in politics, stereos, cars, and perhaps even stamp collecting. We’re looking for affirmational support that we made the right choice. Newbies to our hobby […]

What would happen if we could eliminate the impedance of the wires feeding our homes?m

Paul McGowan / PS AUDIO In yesterday’s post, I gave a bit of background on our path at PS Audio of increasing power transformer sizing. Quite by accident, we had found that oversizing the power transformers in our products delivered audibly superior performance. It was the increased wire gauge with its subsequent lowering of impedance that […]

GETTING IT STRAIGHT: It doesn’t take long to figure out the importance of AC power, and perhaps …

Paul McGowan / PS AUDIO It doesn’t take long to figure out the importance of AC power, and perhaps no device can better demonstrate the advantages of perfect AC than a Power Plant. I wonder how many of the thousands of Power Plant owners across the globe really understand what’s important in power—why their AC […]

MECHANICAL vs. SOLID STATE: “Relays are expensive and cumbersome”

Paul McGowan / PS AUDIO When we need to switch inputs on an analog preamplifier we use a switch. The kind of switch we use affects sound quality. For years we had only mechanical switches from which to choose. Standard switch contacts in those days were nickel or tin-plated while the more expensive and better-sounding […]

NOISE REDUCTION: Remember back in the day when Dolby noise reduction was the thing?

PS AUDIO / Paul McGowan I remember thinking to myself; this is nothing short of magic. Kind of like the RIAA. Boost the heck out of the high frequencies and then run them through a low pass filter to make everything right again. In the process, hiss is lowered. Magic. What’s worth noting about this […]

THE PERFECT SPOT: Your seating position IS compromised

Paul McGowan … If you’ve done your system setup homework your chair sits at a comfortable distance from the loudspeakers. With the precision of a ruler, you’ve tweaked and adjusted the speaker’s position for best imaging. Though we call it the sweet spot, it’s certainly not the perfect spot. Within the boundaries of most rooms, the perfect […]

CLASS D: What we want is for a preamp or power amp to amplify only the AC, or the moving electricity, and we do not want it to amplify or have anything to do with DC on its input or output.  Seems simple enough.

Paul McGowan:  Recently I promised we’d jump into Class D amps and how they work – but before going there I wanted to take a short detour – one that a few of you have been on my case to get out in the open for a while: direct coupling. I really hesitate to write […]

PS Audio: Continuing our thoughts on power supplies and the differences between a classic linear supply and a SMPS”

Paul McGowan writes: Continuing our thoughts on power supplies and the differences between a classic linear supply and a SMPS, I thought it might be helpful to list some generalized plus and minus’s of both.  For this post I will keep the supplies focused on power amplifiers – I do this because there lies the […]

AUDIO RESEARCH: How they got it both right, and wrong

Paul McGowan writes: Starting in the late 1960s and gaining popularity in HIFI circles in the 1970s, the ubiquitous IEC 320 (shortened from 60320) was immediately embraced by manufacturers; not because it is better (it isn’t), but because it permits the use of multiple cable types without change to the hardware. Once manufacturers began shipping […]

PS AUDIO: The problem with headphones

Paul McGowan writes: I am often asked what headphones I recommend and the answer for me is simple: I don’t.  While I certainly recognize the popularity of headphones and appreciate what they can do, I am personally not a fan for several reasons: I miss the visceral feel of the music as well as the […]

IMPOSTERS: When it comes to our HiFi systems and how good they sound, I suspect they are far better than most of us inwardly fear

At some level, we’re all imposters. We fear our projected self-worth—the way we present ourselves or the way we believe others see us—doesn’t live up to expectations. In my 74 years, I haven’t met anyone that doesn’t to some extent suffer from what is commonly known as Imposter Syndrome. Maybe it’s a fear that our HiFi […]

TRADING VITRIOL FOR VIEWS: No, I am not going to mention any websites nor point any fingers. I don’t need to because you already know what I am talking about.

Angry forums with millions of views. If you build a platform for angry voices they will rush to spew their ill temper. One such site, by a famous person in our industry, has millions of viewers and he’s happy about that—not so much about the hate, but the millions. He likes the millions. Is it […]

USERS VS. LISTENERS

Interacting with a front panel has always been important, but rarely how we judge a piece of equipment. Even the klunkiest front panel layouts were tolerated if the unit’s sound quality was up to snuff. The user interface took a distant second to performance. As we rush headlong into the age of the user interface […]
