Tube Power Amp Reviews

Remarkably, I set out to audition the Hyperion HT-88 amplifier ($2800/pair) over two years ago, only to be confounded by shipping errors, miscommunications, and, in the end, a stealthily defective tube. I almost gave up.

The last time I was in England, I happened to be rummaging through some boxes in my mother's garage, boxes containing photographs, my old school books, concert programs, diaries, postcards—all the bric-a-brac you collect throughout your life that you'll never have a need for and can never discard. If anything, such rubbish is perhaps the nearest thing to roots that anyone can have these days. Among the boxes was an amplifier that had been an everyday companion of mine for many years, the vintage Vox AC100 I had used to amplify my Fender bass when on the road.

Ars-Sonum is a Spanish audio company that, as far as I can tell, makes only one product—but it's a doozy (footnote 1). The Filarmonía SE is a tube integrated amplifier that is, in many ways, an homage to Dynaco's iconic Stereo 70 power amplifier of 1959, but the Filarmonía is by no means a slavish copy. Get down to specifics, and it's actually more of a clean-sheet-of-paper design.

When I attend Stereophile's annual Home Entertainment show, I rarely sit and listen to music for very long. Instead, I try to hit every room, press the flesh, find out about new products, and play a little jazz.

Today is Monday, February 5, and it's so buttercupping cold outside that the custodian couldn't get our school's oil burner started. Consequently, my daughter is home for the day, playing on the rug in front of the fireplace. (Santa brought a wooden castle and a fine selection of medieval figurines, some of which are headed for the dungeon as we speak.) I'm at my desk in the music room, on the upwind side of the house—and the wind is murder. The west wall is cold. The north wall is cold. The floorboards are cold. But the air inside is warm as toast: I'm driving my Quad ESL speakers with a Joule Electra VZN-80 amplifier ($12,000) that isn't at all bashful about squandering a goodly amount of energy as heat. I can't think of a more delightful quality for an amp to have, at least on a day like this.

When I unpacked the Rogue Audio Atlas, I didn't know how much it cost. After examining its chassis of high-grade steel, its silver-anodized aluminum faceplate, its sleek and slightly rounded edges, and, above all, its two chunk-o'brick transformers—for such a little thing (a foot-and-a-half square by half-a-foot high), it's heavy—I guessed around five grand. Then I called Rogue Audio and learned that it retails for $1395.
