I am awaiting delivery in today's post of five AudioQuest Dragon power cords with mixed emotions. The unease is not about them; it is because I'm leery of rocking the boat presently anchored in the placid oasis of audio synergy, where all parts are working and everything important to me in playback is present. From... Read More »

The Akitika GT-102 Power Amplifier


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 »


The iFi PowerStation AC Line Conditioner


Go back some 50 years, and the American audio scene involved an assortment of acronyms from around New England: off the top of my head, AR, ADS, APT, CSW, DBX, EAW, EPI, KLH, and NEAR come to mind, with the BAS (Boston Audio Society) and MIT providing cross-pollination.

Aidas Audio Gala Gold LE MC Phono Cartridge


When it comes to turntables, I have to admit that my top MC reference remains the Aidas Mammoth Gold. It is the benchmark by which I compare all comparable MC cartridges. It lacks nothing I can hear and is listenable to the maximum. The Gala Gold LE is their limited-edition cartridge in honor of the... Read More »

Don't Pass, Go! The Pass Labs XA30.8 Amplifier


During the initial days of my shelter in place, I stepped outside for a walk, only to find a short monolith in the middle of my driveway. It was a hulking, brown box, and obviously delivered by truck. No knock on the door, no ring of the bell... just something I discovered in my driveway—not... Read More »


Goldmund Mimesis 37S NextGen Analog Preamplifier and Telos 280 Stereo Analog Power Amplifier: Never Say Never


I was once upon a time in a galaxy far, far way, an unabashed, dyed-in-the-wool tube lover. The mere mention of solid-state electronics sent my upper lip into involuntary quivering. Still, it was important to separate my job as an audio reviewer from my personal preferences. Over the years, products from Levinson, Rowland, Cello, PASS,... Read More »


LTA MZ3 Preamplifier


For those who have read my other reviews on Positive Feedback, one thing that is probably apparent, is my love of tubes. I find that tubes bring a sense of space and realism that is rare in solid state amplifiers. Now tubes are not perfect, they have their drawbacks. For example, if you are using... Read More »

The Clarus Duet - A Journey Though High-Current Line Conditioning


"If the power supply of an amplifier is designed correctly, there is no need for a power conditioner." The quote above is a paraphrase, of a paraphrase, of something that has been said since the first power conditioning devices for audio equipment crawled out of the ocean and began to breathe air. While the quote... Read More »

(Tw)eek! It’s a Useful Product: The Block Audio C-Lock!

icOn4 Autoformer Based Passive Preamplifier


I am sure I do not speak for everyone, but personally, I rarely find myself turning up the volume on any of my preamplifiers past 50%. I also find that most of the time I am trying to turn down the source before it gets to my power amp rather than add gain to it.... Read More »


Cardas Clear Beyond: What's In A Name?


When I first relocated to NYC from Chicago in 1994, I was deep in the boil of my audio obsession. The timing of my move couldn't have been better.
