How can flat-measuring speakers sound different?

PS AUDIO / Paul McGowan And for that matter, how can same-measuring-anything sound different? The answer lies in a couple of areas. First, we do not measure all parameters that impact sound quality. In fact, as you will see below, we miss some of the most important opportunities for quantifying performance. Second, even if we […]

It is an important aspect of engaging with a piece of audio kit.

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. […]

I know I’ve told this story a million times but it probably bears repeating.

PS AUDIO / Paul McGowan Back in the 90s, when we first started investigating the importance of AC power, we were shocked to find major sonic changes when running our equipment’s AC power through a conditioner. Relative to plugging straight into the wall AC socket, running the AC through a passive line conditioner we immediately […]

UGLY: In the same way we need to go through some ugly and intrusive processes to attain pure water, air, and sound, it is the output we’re concerned with, not how we got there

PS AUDIO / Paul McGowan Purity is defined as freedom from adulteration or contamination. In other words, pure is free from anything other than itself. Pure water, pure air, pure sound. So what happens when we use impure methods such as EQ to achieve sonic purity? Should we be branded as heretics? I recently ran into this […]

BELIEVE IT OR NOT: High-end doesn’t have to mean high-price.

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 […]

In the end, I am thankful that never happened.

PS AUDIO / Paul McGowan After all these decades of building phono stages, I am still confused. Why didn’t turntable manufacturers build phono stages into their turntables in the same way CD player manufacturers built DACs into their transports? I suppose one of the answers might be that most turntable manufacturers made neither arms nor […]

HELIUS DESIGNS: In conversation with Howard Popeck – part three

Geoffrey – what is your response to the statement ‘How many channels do you think it takes to make a music listener happy; One. Mono’s fine. I’ve never heard anybody bitch about Louis Armstrong, saying, “I would enjoy it if it were only stereo” Now this question is interesting from several perspectives and I’m going […]

PSU caps

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 […]

DIY INTERCONNECTS: Using Teflon braided hose

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 […]

UNDERSTANDING: Bad recordings through great systems

We often think of the revealing nature of a great system as a double-edged sword: wonderful recordings sound better while poor ones sound worse. The idea of a system’s ability to magnifying a recording’s good and bad points is problematic when it comes to simply enjoying the music. This is why a lot of folks […]

BIAMPING: I remember my delight the first time biamping speakers was explained to me

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 […]

AUDIOPHILE FUSES: Nonsense or what?

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 […]

CROSSOVERS: Types of resistors for crossovers?

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 […]

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 […]

UNDERSTANDING: The importance of house wiring

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 […]
