The Acoustic Revive Chronicles: The Eleventh House!


As many of you know—and as the title reference to "The Acoustic Revive Chronicles" suggests—over the years I've written quite a lot about the innovative Acoustic Revive audio accessories designed by the brilliant Mr. Ken Ishiguro in Isesaki, Japan. In fact, I've spent more time writing about Mr. Ken's Acoustic Revive accessories than I have... Read More »

My Favorite Tubes and Their Substitutes


I love and appreciate tube based audio gear and own sixteen pieces of tube gear between my two reference systems. Without a thorough knowledge of tube types and their substitution possibilities, you may be over-paying for your new or NOS tubes you employ, or just pick the wrong ones. This data is based on my...

How Wall Street Destroyed the Record Business


"The digital music business has been a war of attrition that nobody seems to be winning," said David Goldberg, the former head of Yahoo music. "The CD is still disappearing, and nothing is replacing it in entirety as a revenue generator." Its no mystery that the wiring of our world has brought enormous changes in... Read More »


Music Enhanced To an Astonishing Level: The Transcendent Kubala-Sosna XPander A/C Unit


The First Blueport "Audio Transcendence" Award (With a response by Marshall Nack) What does it mean that the onset of Global Warming coincides with the arrival of a theoretical Golden Age of audiophile possibilities? I'll think about that awhile as the emergence of DSD (direct stream digital), after a quarter-century languishing in audio twilight with... Read More »


Kubala-Sosna XPander Power Distributor - Neutrality and Coherency taken to the Next Level


Talking About Power Distributors (With a response by Jim Merod) Every time I'd get in a new power product, Joe Kubala would come over to check it out. And always, after assessing it, the same question lingered in the air: when—not if—would we see a Kubala-Sosna Power Distributor? During the five years it took to... Read More »


Lampizator's 5th Generation DSD DAC: A Game Changer


The New Lampizator Generation V DSD DAC (Photo: Brian Moura) In May I attended The Show in Newport Beach with a list of new products I wanted to hear. Near the top of that list were the widely applauded, tube-based Digital to Analog Converters from Lampizator in Europe. They had captured the attention—and dollars—of many... Read More »


Why I Left TAS


I discovered the high end in 1978. But I seemed to have a natural inclination towards high-quality experience. My father was a largely self-trained EE, who was hired at RCA Camden as his first job in the US in 1951. He built our hi-fi systems at home including what I recall as the first stereo...

Audio Intelligent Vinyl Solutions' Premium One-Step Formula No. 6


"No man ever steps in the same river twice, for it's not the same river and he's not the same man." – Heraclitus That's how I feel about most things in life; I appreciate the subtle differences and I don't like to experience the exact same things over and over. While I certainly have my... Read More »


Covalent-Audio Nucleus Headphone Amplifier-Preamp Review


A golden age only happens in retrospect: By the time you realize you're in one, you ain't. Hell, most of us have a hard enough time deciding the winners of the past (ever been stuck in a Linn Sondek LP12 vs Micro Seki DDX-1000 debate?) so speculating on Audio futures is always a dicey proposition....

But, What About The Music?


I've just spent a little time reading posts—both the originals and the comments on them—in some of the more than fifty audiophile groups that I know of on the internet. I'm sure there must actually be many more than just half a hundred of such groups, but from what I've seen, fifty is more than... Read More »


Response to Dr. Robinson's Essay on Harry Pearson - It's Like You Knew Him!


A Portrait of Michael Mercer: THE Show, Newport Beach, CA, 2013 I have to admit, it felt great to laugh out-loud while reading Dr. D's (as I call him) farewell essay on Harry Pearson. It was also refreshing; as he stated, because Dr. D never worked for Harry. He was able to take a more... Read More »


The Audio Circular: No.11 in a Series of Parallel Narratives - The Wyred 4 Sound DAC-2 DSDse


I admit it; I can be late to the party. The vast majority of gear I have written about is not new to serious audio buffs and some has had much previous press. There are two broad causes for this: One: I am not "initials" famous. You can't utter "gb" and watch as everyone turns... Read More »


Impressions: Harry Pearson


Harry Pearson, a characteristic pose. RMAF 2009, Denver, CO With the death of Harry Pearson, Michael Mercer and I talked and decided that we would put our thoughts about his passing together in a pair of brief reflections, and publish them together. Others have already done so, and will probably continue to do so, at... Read More »


Harry Pearson, Jr.: Godfather of High-End Audio, Sonic Explorer, and Southern Gentleman


Harry Pearson was an extraordinary man. He was always curious, and could turn an acidic, negative situation into fine wine and smiles with a quick-witted retort to a verbal challenge anytime. (Well, except after imbibing too many chocolate martinis). He loved knowledge, and was always reading something in the morning hours following his daily sunrise-walk.... Read More »

Only my oldest, dearest friends call me "Clarkie", so be careful – but it does make for a better title, so, yeah. / The author When I first met Harry it was on the lawn of the St. Tropez Hotel at a C.E.S. some years ago. But we had had a history that, in its... Read More »
