The Devialet D-Premier is sure to go down in audio history as a game changer. When it was introduced in 2010, little did we know that the D-Premier would alter the integrated amplifier landscape forever by redefining the concept of what an integrated amplifier is.

Readers might remember my review of the McGary Audio SA1 in 2018 (HERE). It was a wonderful amp and highly recommended.

What's new in audio? Not much in the past 40 years or so. When was the last technological shake-up in audio? Compact Disc, maybe? From there, digital technology has spawned endless formats of claimed resolving power that is rarely capitalized on. What I have had a hankering for is not another format war, rather, HARD...

Linear Tube Audio has a delicious solution for our headphone amplifier needs—the microZOTL MZ3. We love it! Let me tell you why it now has a well-deserved home in Ann's study. Prologue… I've written previously about our journey into headphone-only audio as the result of our retirement, downsizing, and move into apartment living. We found... Read More »

Six months ago, I was an infrequent headphone user. At best I listened to an old set of ear buds with balance armatures while riding the elliptical during one my very infrequent visits to the gym.

I recently reviewed the entry level Boulder 508 phono stage, and it surprised the boots off me by its price / performance ratio. It's so good, in fact, that it ended up finding a permanent spot in my system. Since then I have been following the roll out of Boulder's latest product, the 866 integrated... Read More »

The last decade summers at my place have been hotter than ever before. At 6300 feet, what used to be two weeks of high temps has turned into 10 weeks of even higher temps. I know this is just a Chinese hoax, but damn, the heat my tube monoblocks generate is just too much for... Read More »

Some dealers and manufacturers have reported that people have been making those all-important decisions, pulling the trigger on new equipment. Perhaps because quarantines and lock-downs have freed up a resource many adults lack. That resource... Read More »
