VAC PA80/80 power amplifier:
As noted above, the 80/80 comes outfitted with KT88s, which is how I auditioned it—mostly. VAC also sent along a quartet of the new Golden Dragon KT90s. I tried 'em and liked 'em—mostly. Extended listening revealed the KT90s to lack the expressive subtlety of the KT88s, not to mention the gloriously open sense of air manifested by the older tube. The '88s are definitely the way to go, an opinion shared by designer Kevin Hayes. "I've gone back and forth on the subject of the KT88 vs the KT90—much as the KT90 itself has progressed. When I first heard them, I preferred the KT90, but the more I listen, the more I prefer the KT88. The '90 has an absolutely solid control of dynamics and a punchy upper bass, or midbass, area. It is almost aggressive in the lower ranges. But over time you hear that the tube lacks subtlety, lacks air, and lacks a natural sense of depth perspective." Emotional baggage Music is first motion, then emotion That's not to say, however, that the VAC possesses that old gloriously-colored-and-proud-of-it tube sound—or at least, not too much of it. I wouldn't use terms like "caramel" or "golden" to describe its character. On the contrary, it's open on top and has emphatic, well-controlled bass, neither of which describe "classic" tube sound. Another contrast with the classic designs is the 80/80's dead silence. Even the 91dB-sensitive WATT/Puppy 5s remained quiet, exhibiting no tube roar whatsoever. Yet there's no mistaking the VAC for a solid-state product: it has that tube "glow"—and you can debate until the cows come home whether it's a coloration or a higher form of accuracy. My friend Ruben could spot it so consistently that he would enter my foyer and state, "You're listening to the VAC again!" Then he'd sit down, tell me to be quiet, and listen intently until the disc ended. One of my favorite discs these last few years—and certainly one of the most emotionally (nearly) overwrought—is Leonard Bernstein's Mahler 3 with the NYPO (DG 427 328-2). Mahler referred to the Third Symphony as his "monster," and I'm not sure he was kidding. It's huge—the first movement alone is longer than Beethoven's Fifth Symphony—and it calls for an immense orchestra, a contralto soloist, a women's chorus, and a boys' choir. Emotionally, it ranges from moments of tender, yearning melodicism to a series of increasingly thunderous—but never vulgar—climaxes.
