There are many great mysteries in the world: how the pyramids were built, the Easter Island Moai, why whatever hair I lose on my head seems to pop up somewhere else, and I am sure there are plenty more. There are two great mysteries in audio that are currently bugging me and, if I thought […]

Saturday afternoon we had about 40 visitors from CAS listening to Music Room One. Chuck Zellig, whom you might remember co-wrote a couple of articles in TAS called Computer Audio Sound Quality, was at the event and pulled me out of the crowd to make a comment about what he heard. “The system sounds incredible […]

Morning! 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 system, the […]

In the process of answering the many comments I receive (which are much appreciated) one was made that really struck home. Here is the comment from frequent contributor Mark Fisher that was made after I wrote “it’s amazing what it has done for the system.” “This seems to happen every time there’s a change. When […]

After yesterday’s post I was thinking about the term Separation as it applies to the instruments and singers on a soundstage. I spoke of how the elements in the recording were rounded and separate such that they seemed as if I could reach out and touch them. They were palpable. It occurs to me that […]

I thought today I’d touch on the term Palpability for a couple of reasons: I use it to describe certain aspects of what we hear in our stereo systems and more pertinent – I have just been exposed to a greater degree of it than ever before. I was going to title this post Eating […]

Continuing with Audiophile terms I find Transparency a much used term that perhaps is a bit nebulous and easy to overuse. One of the first things you notice about many of these terms is they are somewhat self descriptive; as any really good and valuable word should be. Transparent means you can see through it […]

I use plenty of Audiophile terminology in my writings. Lots. From time to time readers have asked me to define those terms as they apply to what we hear and what they mean to me when I write them. Perhaps it’s time to start a bit of that and see where it leads us. The […]

Once the homemade power cable was finished I immediately connected it to the preamp. Interesting. The most immediate thing I noticed was an increased openness without brightness that was never in the design before. Separation of instruments was greater, soundstage deeper, all the good things you’d hope for. However, there was a tightness to the […]

In my new found quest to figure out why power cables made a difference in my preamplifier circuit I began to suspect that I wasn’t adding fullness or, for that matter, anything to the preamp’s sound but rather guessed that what must be happening is one of degrading in the first place. By that I […]

During the latter half of the 1990’s I was busy with a new preamp design that was more of a personal project than anything for the company. That project would become, after a number of years, the PCA-2 preamplifier we released after the turn of the millennium, but during the 90’s it was just something […]

I was going to step off into the deep end this morning with the start of our cable series but many of you asked about the results of the latest amp shootout so I thought I’d give you a brief update on that progress. The quick overview is that we made significant progress, but we […]

It’s not something attainable in a product – I have no desire to work on achieving it – it is a fool’s errand. I bring this to your attention because of all the kind notes people have been sending me about the new power amplifier and my quest to “perfect it”. I am not trying […]
