Feedback summing point common-mode gain Introduction Negative feedback, when properly used, can significantly improve the performance of an amplifier. The emphasis must be on “properly used”, as improper use of feedback can make things worse. A common mistake is to use too little feedback, either because the open-loop amplifier has high distortion or because of […]

Brent Butterworth writes: Merriam-Webster’s Collegiate Dictionary, 11th Edition defines audiophile as “a person who is enthusiastic about high-fidelity sound reproduction.” The word first appeared in print in 1951, in an era in which audio gear bore little resemblance to what we use today. Since then, the working definition of audiophile also seems to have changed. […]
Paul McGowan: If I had to think of the worst thing I might add to a power amplifier, an output transformer would be right up there – yet the vast majority of tube power amplifiers sport them. Tube amps interface their output stage with your loudspeakers through a matching transformer, not because it sounds better […]
Paul McGowan …… If you had a chance to read yesterday’s post you’ll remember we’re in the process of setting up Music Room number Two, where we have a pair of floor standing 2-way Thiel loudspeakers. That room is considerably smaller than Music Room One, measuring 12 x 15 feet, compared to Music Room One’s […]
“From the Isoclean products to the Weizhi over to the Stage 3 power cables and now to the Thales IC. The S3 and Thales are by far the best AC/IC I have ever heard in my system. No cable has come close to them. The new AC passive units Brain sells are said to better […]
“I’m ready to move on from my current system: Bryston 4BST, Proceed Pre, Revel Performa F30’s and Ayre QB-9 DSD DAC. I’m planning to keep the DAC, and swap the Bryston and Proceed out for a decent integrated SS amp (just don’t want to “do” tubes, even though I think they can sound great). […]
Jonathan Scull (Stereophile magazine): Kathleen (K-10) and I first met Jack Renner—Telarc’s Chairman, CEO, and Chief Recording Engineer—at Iridium, a tony jazz club here in New York. He was recording Benny Golson and the Jazz Messengers doing a rousing a tribute to Art Blakey. Now what would you think a guy who’s won 31 Grammys […]
The law of diminishing returns: you have to spend disproportionally more to get smaller and smaller improvements. MORE
Paul McGowan writes …… My son Scott loves music; perhaps more than I. He’s willing to listen even if the recording is awful and is able to turn off the rejection mechanism so ingrained in my head as an Audiophile. Part of me wishes I was just as able to be that selective – because […]
I’ve owned a lot of speakers over the years but I have never experienced anything like the midrange reproduction from my horns. With a frequency response of 300 Hz. up to 14 Khz. from a single distortionless driver, it seems like a no-brainer that everyone would want this performance. Why don’t you use horns? […]
Robert Baird writes: Tune those young ears, Mr. Anderson! After a 30-year career in audio engineering that’s seen his name appear in the credits of over 1700 albums, Jim Anderson, who won the 2013 Grammy for Best Surround Sound Album, for his remastering of Patricia Barber’s Modern Cool, thinks education is the key to stemming […]
Sitting in an oversized bulbous chair outside the interview room waiting for my turn to speak with Neil Young was surreal. I didn’t grow up a big fan of Neil. I was introduced to his music through my favorite band Pearl Jam. PJ frequently plays Rockin’ In The Free World as an encore at its […]

I am sure somebody will start saying I have an agenda or I am selling something so I will leave it as an open question without comment. BTW I do not count a tweeter protection cap as a crossover, it is the rest I am talking about. So saying to protect the tweeter doesn’t […]
Paul McGowan ….. I promised we’d get started on system tuning and figuring out how to relate what I am doing on the new system to what you can do on yours. Hopefully this new series will be a help to you in getting the most out of your high-end audio system. The first thing […]
During a recent high end demo, a track I’m very familiar with (Teardrop by Massive Attack) and have heard innumerable times, was played through a “top of the range” hi-fi system. There was pretty obvious distortion of the piano notes in the intro. I pointed it out, and we played the same track on […]
Do any Japanese amps from the 70s onwards do prat as Flat Earthers know prat? Or was it just a UK thing? Dip in and out HERE
I have a Conrad Johnson PV-12A pre-amp. It is phase correct for the phono stage, phase inverting for the line stage. My power amplifier is a conrad johnson MF2100. It is phase correct. So my first idea was to connect the speakers to the power amplifier the wrong way (black to red, red to black) […]
Paul McGowan …… Thanks for all the kind words about my recent post about music and how smart I must be to have written such a piece. Sorry to disappoint but that article was actually written by our resident musicologist Larry Schenbeck, who IS really smart. Thanks Larry, the mailing service grabbed his article instead […]
