LATEST ADDITIONS

Introduced at the 1988 Summer CES, this preamplifier from San Francisco-based Parasound costs $395 and is manufactured in Taiwan. It does away with mechanical switching for source select and tape functions, replacing it with CMOS integrated-circuit switches similar to those used in the British Linn LK1 and Quad 34 and 44 models. Construction is to a good standard and the circuit is carried on two main pcbs and three small ones. Following a signal from the phono inputs, the MM-only RIAA amplifier is based on discrete FETs, its output joining the line-level signals at the switching ICs, these controlled by DC voltages controlled by front-panel pushbuttons.

Music to Listen to KLH By
Excerpts from recordings by Everest and Concert-Disc.
KLH VSR-101 (LP).

Don't be misled by the title of this. It's fine for listening to KLH by, and it is also fine for listening to any other top-notch reproducer by. It is, in fact, the best, and most musical, stereo demonstration disc that's come along to date.

Few people in the high end know the difference between glorious excess and wretched folly as well as Harvey Rosenberg. Harvey's audio equipment always strives towards the glorious folly of providing the most romantic sound possible with modern technology. This may explain why his relatively small company, New York Audio Laboratories, can build an amplifier like the Futterman OTL-1, which costs a glorious $12,000 a stereo pair and actively competes for the title of best amplifier in the world.

Founded by Nelson Pass in 1974, Threshold is one of those companies audiophiles tend to take for granted. Best known for the much-imitated Stasis (sliding bias) amplifier designs, Threshold became one of the industry leaders during the early 1980s. Since then, they've been upstaged somewhat by such rivals as Krell and Mark Levinson, and the public's impression of the company's stability wasn't helped by the departure of several of its principals, including Nelson Pass.

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.)

We who love recordings of massed voices have learned the hard way that some succeed in blending vocal clarity with acoustic resonance, while others deliver echo-muddied jumbles. Happily, some very fine choral recordings have come my way in the last six months. Along with John Atkinson's acoustically stunning engineering of recordings by the vocally gifted Portland State Chamber Choir and the all-male ensemble Cantus, these aural documents do composers proud.

Sibelius: Symphonies Nos.4 & 5, The Swan of Tuonela, Tapiola
Berlin Philharmonic, Herbert von Karajan
Deutsche-Grammophon 138 974 (LP, Symphony 4). Both symphonies reissued on CD (Deutsche Grammophon 457 748 2)

Magnificent, musically natural recordings with some of the deepest, fattest bass and richest, warmest orchestral sound that's been committed to recordings for many years. The discs are a shade more lucid than the tapes, but not much. Take your pick.—J. Gordon Holt
