This review and its companion that will follow next week spotlight two very different and equally recommendable recordings of contemporary music with a common theme: the quest for freedom and justice in perilous times. This week's special, Lament/Witches' Sabbath (New Focus Recordings), due out today (November 9), contains four works by Mathew Rosenblum, an East Coast composer who occasionally ventures into forbidden territory as he blends percussion, acoustic instruments, electronics, voice and microtonal elements in extremely visceral, moving, and sometimes gut-wrenching ways.

By far the most complicated of the three preamps i review in this issue in terms of facilities offered, NAD's "Monitor Series" 1300 ($398) provides two buffered tape loops, an external processor loop (which can also be used as a third tape-recorder loop), a headphone output, a "null" switch, switchable bass equalization to extend the low-frequency range of small loudspeakers, and treble and bass controls, each with a choice of three turnover frequencies: 3kHz, 6kHz, 12kHz, and 50Hz, 125Hz, 250Hz, respectively.

Japanese audiophiles venerate American high-end audio components, paying huge sums for vintage Marantz tube amplifiers, racks of Levinson ML-2s, and early Audio Research tube preamplifiers. The balance of trade, at the high end anyway, hasn't been reciprocated: Japanese high-end amplifiers and preamplifiers have not received as positive a reception in the US. Perhaps it was a matter of styling, but the sonics of the Sony Esprit line and the class-A Stax amplifiers did not receive the following they might have, had the products been American.

"I've got six hours to get ready for 30 hours of show time so an attendee can listen for 10 minutes." Thus did Doug White, proprietor of the Philadelphia-area dealer The Voice That Is, describe the challenge of setting up a system for a show such as Capital Audiofest. (When I asked, Do you use a spectrum analyzer?, White said Yes, and smiled and pointed to his brow.) The results of his expertise—no other word for it—were in full flower in a system that, though far from humble, featured the least expensive loudspeakers I've heard in a TVTI system: Tidal's Vimberg-series Mino ($29,000/pair).
