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. Oh, and there was one nasty four... Read More »


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.

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.
