Up the Long Ladder Maurice Jeffries at GTT Audio:  a portrait. Long Valley, NJ, 2021 I won't rehash here either the science behind KRONOS Audio's remarkable line of turntables, or the engineering insights that led Louis Desjardin, the turntable design world's current enfant terrible, to pursue his revolutionary approach to turntable design. Instead, I'll begin... Read More »

Greg Weaver, a fresco portrait. Chicago, 2018 (photograph and fresco image processing by David W.

Ye Olde Editor at Rocky Mountain Audio Fest, Denver, CO, 2019 (photograph by Scot Hull of Part-Time Audiophile; image processing by David W. Robinson) I haven't been doing much traveling over the past couple of years. No news here:  COVID-19/Delta, you see. And thus, no audio shows. But just recently I did get an opportunity...

Ye Olde Editor in a tobacco moment (photograph by John Robinson) These thoughts are short and to the point. High-end audio is filled with reviews (many of those should read "reviews"), arguments, and endless debates about reference standards, ratings, lists, best-ofs, and so on…endlessly. There are über, no-holds-barred components/systems, at (usually) astronomical prices. Then again,... Read More »

Many years ago, Goldmund, one of Europe's leading manufacturers of reference-quality audio products, offered individual "Cube" amplifiers to plug into and directly power each of the sections of its then US$80,000 (more like US$500K, today) Apologue speaker system.

Colored vinyl, or a few words about the phenomenon of colored vinyl with the Komeda Quintet's Astigmatic in the version released on the artists 90th birthday as an example. Colored vinyl LPs are flooding shops and the Internet. What's the point in that? Do consumers really get more or is it just a way to... Read More »

There's been a vast amount written about what an audiophile is. (Personally, I and my friends have always preferred the term "HiFi Crazies," which, at least to us, seems more accurate and less pretentious.) Audiophiles—depending on who's writing, where, and when—have been described as everything or every combination of things from music lovers to equipment... Read More »

There are issues that drive me crazy, truly. I try not to give in to them, I look away and look for more interesting activities, but eventually, sooner or later, they come back to me. I am thinking mainly about how pavements are treated. Once the NOT office building, commonly known as the Szkieletor, today... Read More »

After 45 and more years as died-in-the-wool analog listeners, we moved from an all-vinyl listening system to an all-digital listening system. And as we've explored digital recordings, we've kept our "audiophile-off-the-deep-end" hats firmly in place,... Read More »

When I was a Kid Hi-Fi Crazy many years ago, "specs" were really important to me and to all of my Kid Hi-Fi Crazy friends. Being kids, we naturally had no money, and couldn't afford to buy anything—or at least not anything that wasn't either a kit or second-hand. Even so, we were all very... Read More »
