Which loudspeakers do audio professionals listen to? And why should we care? After all, it's not as if recording engineers are the kind of refined, sensitive, music-loving types who read Stereophile. As much as they may love music, many audio pros appear only to view the original sounds of musical instruments as raw materials to be creatively reshaped and manipulated. (Okay, there are exceptions. But recordists who care about the sounds of real instruments usually record them in real acoustic spaces rather than in studios, and use as little signal processing as they can get away with.)

In 1988, Bob Carver set out to design the best amplifier he possibly could, without regard for cost. It was more of an ego exercise than an attempt to build a product with wide commercial appeal. The result was the four-chassis, $17,500 Silver Seven.

Interestingly, Bob Carver chose vacuum tubes to realize his dream of building the ultimate power amplifier. The Silver Seven uses fourteen KT88 output tubes per channel, and puts out 375W into 8 ohms. Bob built three pairs of Silver Sevens, not expecting to sell many at the $17,500 asking price. When those sold quickly, another 10 pairs were manufactured. Now, demand is so great that Silver Sevens are built in groups of 30 pairs.

It's a tense moment during a suspense thriller. A cannibalistic serial killer has escaped from a maximum-security detention unit and eluded capture for long enough to work up a healthy appetite. Two small children are playing hide-and-seek in an overgrown lot behind their home.

Mahler: Symphony No.1 in D ("The Titan")
Columbia Symphony Orchestra, Bruno Walter, conductor
Columbia MS-6394 (LP). John McClure, prod. TT: 52:15

This is one of those rare combinations of a superb recording and a stunning performance. As far as I'm concerned, it is the best Mahler First that Bruno Walter committed to discs during his lifetime, including the last one that he made with the New York Philharmonic. And the fact that this recording is far superior to that accorded Walter when he conducted the New York Philharmonic does not detract one bit from my feeling about this new release.

Joan Baez In Concert, Part 2
Joan Baez, vocals, guitar
Vanguard VTC-1679 (tape), VSD-2123 (LP). Maynard Solomon, prod., Reice Hamel, eng. TT: 48:00.

Well, we finally got ourselves equipped to review 4-track open-reel tapes, via a slightly modified Ampex F-44. All the tapes we have auditioned had noticeably higher hiss than the average stereo disc, but this was not loud enough to be distracting except when the tapes were reproduced at very high levels. Even then, we found the smooth, even hiss to be less objectionable than the ticks and pops from some discs played at the same level.

Rimsky-Korsakov: Scheherazade
London Symphony Orchestra, Leopold Stokowski, cond., Erich Gruenberg , solo violin.
London Phase 4 SPC-21005 (LP). Recorded September 22, 1964. Kingsway Hall, London. Marty Wargo, prod., Tony D'Amato, recording dir., Arthur Lilley, eng.

This is infuriating. Along comes the performance of Scheherazade that we've been waiting for, and the powers that be at London Records decide, God knows why, to bestow upon it the dubious blessing of Phase 4 recording. The sound is positively vast and cavernous, the bass booms, the highs scream, the harp sounds like it's 10' tall, and instruments wander back and forth across the stereo stage as if nobody had thought to tell the musicians where to sit.

The unsung sage who first observed that high-end audio is a solitary vice was probably not implying that audiophiles are antisocial; he was merely acknowledging the fact that a decent stereo stage is usually only audible from one place in the entire listening room—the so-called sweet spot. Stray from that spot, and the whole soundstage shifts to one side, spaciousness collapses, and images become vague and unstable. This is the antisocial aspect: only one member of a group can hear good stereo at any one time. (The gracious host at a listenfest will take a secondary seat, allowing his guests to take turns sitting in the sweet spot.)
