Solid State Preamp Reviews

"So what are you reviewing now?" A polite question, considering that my old friend Randy is definitely not an audiophile.

Back in 2003, while auditioning the Burmester 001 CD player ($14,000, reviewedhttp://www.stereophile.com/digitalsourcereviews/1203burmester">reviewed…; in the December 2003 Stereophile, Vol.26 No.12), I discovered that my system sounded much better if I bypassed my preamplifier and ran the 001 directly into the power amps. I concluded by suggesting that potential customers consider building a system around the 001 itself and forgo a preamp altogether. The response from Burmester fans was immediate and unambiguous: As good as the 001 was on its own, it sounded even better run through its stablemate, Burmester's 011 preamplifier ($15,999). The pair had, they claimed, a significant synergy that I absolutely had to hear. It's hard to argue with determined German logic, and I'd begun shopping for a new preamp anyway. So here we are.

The Bryston BP-25MC preamplifier is a full-function control center with one balanced and four single-ended inputs, including one input for a moving-coil cartridge. The BP-25 is shielded in a black steel cabinet said to reduce electromagnetic interference effects. The power transformer is housed in a small external chassis, the BP-PS. The BP-25's remote control allows volume up/down, along with buttons for mute and absolute polarity. Signal switching and audio connections, including balanced and unbalanced input and output connectors, are heavily gold-plated to provide good long-term connections. A 12V AC/DC screw terminal connector on the rear of the power supply provides convenient use when used in conjunction with the remote start feature optionally available on Bryston power amplifiers.

In August, I reviewedhttp://www.stereophile.com/amplificationreviews/804mcintosh">reviewed; McIntosh's MC501 monoblock power amplifier. In terms of what I'd thought was possible from Mac, this was a revelation. Once memories and lurking preconceptions had been set aside and the amps installed in my system, the MC501 easily established itself as among the finest overall performers I have ever reviewed.

Founded in 1984 by Mark Levinson, the man responsible for the original Mark Levinson products (footnote 1), Cello has slowly become more visible within the high-end audio consumer market, as well as establishing a presence in the recording industry with very high quality microphone preamps, tape electronics, power amplifiers, and equalizers. Taking a holistic approach, Levinson offers Cello systems complete from preamplification and equalization stages through amplification to loudspeakers. He can also set up a complete recording studio for you, including the microphones, microphone preamplifiers, and tape decks. Cello manufactures their own interconnect and speaker cables, cutely called "Cello Strings." Besides marketing his products through high-end dealers, Levinson has established two showrooms, in New York and Los Angeles, dedicated to sales of Cello systems and components (as well as a few selected source components from other manufacturers).

The Placette Audio Remote Volume Control is simplicity itself: a paperback-sized black box with one set of unbalanced inputs and outputs, a toggle switch (and a remote) to change the level, and a row of LEDs that light up to indicate the relative volume level. The signal path, too, is simple, with only a stepped attenuator between input and output. But this is not just any attenuator—it's a 125-step model built entirely with super-premium Vishay S-102 foil resistors.

The Jeff Rowland Design Group has long been renowned for the exquisite quality of its chassis. The company was one of the first to promote fully balanced topologies in preamplifiers and amplifiers in the high-end market, one of the first to offer a sonically acceptable remote control, and one of the few to offer a battery power option for their amplifier line.
