PS AUDIO / Paul McGowan Their excitement comes from understanding the challenge of making an air piston (which is what a speaker driver is) that can start and stop in perfect synch with the instructions from your power amplifier. To accomplish that feat one would prefer a cone (the piston part) that had zero mass […]

PS AUDIO / Paul McGowan If you had a chance to read my post of several days ago titled The Bypass Cap you might have been thinking it was about headwear. Or, you might have gotten my analogy of using a super tweeter to augment a standard tweeter. Here’s another for you. If you were to take […]
PS AUDIO / Paul McGowan Many of the products of science we take for granted were discovered by accident: penicillin, Viagra, anesthesia, the microwave oven, chewing gum, brandy, and even silly putty. The key to those discoveries lies in the inventor’s openness to observations unrelated to the original experiment. Take for example, when in 1879, […]
PS AUDIO / Paul McGowan I think that by this time in our lives we no longer believe in Santa Clause, the Easter bunny, or the Tooth Fairy. Like the myths of our youth, old tropes that we might have picked up when we first started our journey down the path of high-end audio can […]
PS AUDIO / Paul McGowan Speaker designer Chris Brunhaver shared with me a funny YouTube video. Check out the Knob Feel channel. Probably worth one or two quick views for a good laugh. However, it does bring to mind the importance of feel. I doubt many of us are immune to the touchy-feely aspects of high-end audio. […]
PS AUDIO / Paul McGowan I am guessing a number of people believe that to qualify as high-end audio gear means it must be expensive. I want to argue the opposite. The true meaning of high-end audio has nothing to do with price and everything to do with performance. That the highest performance gear is […]
PS AUDIO / Paul McGowan In yesterday’s post, I wrote about the importance of lower impedance in the AC line voltage. I mentioned that lowering the impedance is far more important than cleaning up the AC line noise (a subject for yet another post as this goes against nearly all the conventional wisdom). I got a […]
Dear Colin, PSU caps. There are two (2) large rectangular caps at the ac inlet of the PSU of my DIY amp. They are labeled as such; 0.1uF 250V~X2. What does the X2 mean? Yeah I know, stupid question, but I’m at least looking for a intelligent answer and seeing all the past Colin’s Clinic […]
Hi Colin. I love your ‘clinic’. Neil promised that you might be offering education for us novices. So may I ask – have you ever thought about using braided hose to run your interconnects. I am talking about type usually found as brake lines on motorbikes and car braking systems, i was messing around with […]
Paul McGowan The notion of using one amplifier perfectly matched to the tweeter and another to the woofer made such elegant sense. Tubes for the top end, solid state grunt for the bottom. Brilliant. That was at a time when the choices in amplifiers were limited. Big, powerful solid state amps sounded pretty poor reproducing […]
Hello experts. I have used audiophile fuses for years in various equipment without problem, generally appreciative of sound quality improvement. Recently, I’ve encountered problems with audiophile fuses blowing in my Coincident Turbo 845SE amplifier. At this point I’ve had two failures of Synergistic Red Quantum 6.3a 250v sloblo fuses in this amp. Recently I discovered […]

When audio signals pass through a capacitor they sound different depending on which kind of capacitor is in use. Why? And, for that matter, what is a capacitor and how does it work?
Here’s one for you electric wizards to kick around. Whilst attending a recent hifi exhibition I was doing some power cord shopping. At one particular display I was being told by a very well known cable company representative, I’ll not mention the name so it doesn’t influence any responses, that the rule of thumb is […]
Dear Colin, I have just fitted stock 2R7 Panasonic 0.1% metal film resistors to replace the “green” 2R2 wirewounds in series with the Millennium tweeters in my WD25Tex speakers. I expected a change ( a bit warmer) but was not prepared for such a drastic change – is this due to the 0,5R increase or […]
Which is the better interconnect for home audio systems? Balanced XLR or unbalanced RCA? Paul voices his opinion and explains the differences between the two and their reason for existence. Have a question you’d like Paul to answer for you? Go to https://www.psaudio.com/ask-paul/ and post it. Watch Now Paul McGowan
What is damping factor and more so what is the major influence for it ? Aanswers on a postcard please ..or just leave a simple reply Real question is how does one maintain or create the tube sound in a transistor amplifier ? Dip in (and then out) HERE
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 […]
Paul McGowan / PS AUDIO Over on the PS Audio forums, there’s a thread about cable lifters. You can read it by clicking this link. Elevating the speaker cables off the floor works to improve the sound. Should you run out and grab a set of cable lifters today? Much depends on the state of your […]
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 […]
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 […]
PAUL McGOWAN / PS AUDIO Zero calories? Went to cook some scrambled eggs this morning and first sprayed the pan with one of those spray oils. Always conscious of my weight I checked the calorie content: zero. Zero? Really? It is, after all, oil and oil is NOT zero calories. Turns out the agency that […]
Paul McGowan / PS AUDIO: When we built Music Room One we made a point of electrifying it properly: Dedicated circuits with heavy gauge wire. Had we the time and budget we would have also used grounded conduit as a shield against noise. The importance of a proper AC foundation cannot be understated. The two properties we […]
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 […]
