Phono Preamp Reviews

The German company AQVOX Audio Devices has produced an innovative moving-coil/moving-magnet solid-state phono preamplifier, the Phono 2Ci, that's as intriguing for its technology and performance as it is for its relatively low price: $1400. The zero-feedback, op-amp–free circuit uses a compact switch-mode power supply that's built into the chassis and features conventional voltage gain for moving-magnet cartridges via its RCA jacks, and current gain for moving-coil cartridges through the balanced XLR inputs. Rear-panel switches select between RCA or XLR inputs and offer a convenient ground lift. Either the single-ended or the balanced outputs can be used with either input. Unfortunately, the tight spacing of the RCA input and output jacks, which are mounted on the circuit board, will somewhat limit your choice of cables: Pairs of thick-barreled plugs will have difficulty fitting.

"Everybody's gotta get into the act!" Jimmy Durante used to say. That's what's happening with phono preamplifiers—they just keep being built, and I keep getting them for review. Up for evaluation in next month's column are new models from Perreaux, Musical Fidelity, Graham Slee, and a Chinese one, Ming Da. You can bet there'll be more.

If compact discs are so damned dynamic and vinyl is so dynamically limited, why do they sound just the opposite? Why do LPs sound so "live," so explosive, so "there," and CDs so dead? Even the best CDs usually sink to second-rate when you switch to their vinyl versions. I've heard it, you've heard it. Only those in deep denial, those who refuse to listen, don't. They'd rather read the published specs and consider the actual listening some kind of mass delusion among Luddite LP fans.

The $3000 moving-coil (MC) PhD, available from Chad Kassem's Acoustic Sounds operation, is a monumental achievement that, for me, sets new standards for the cleanness and transparency possible in a phono preamp—and I've had a lot of experience with phono preamps.

I don't know Graham Slee from Gram Parsons, or which House he was in at Harry Potter's Hogwarts School, but let me tell you: If you'd just been listening to a bunch of budget phono preamps, as I had, then came upon the GSP Audio Era Gold Mk.V, you'd think someone had switched out not just the phono preamp but your entire system. You might think you were listening to a different pressing or a different cartridge. How can this be?

The Manley Steelhead tube MM/MC phono preamplifier was first demonstrated at the 2001 Consumer Electronics Show. Nine months later, my long-promised review sample of Eveanna Manley's new baby was delivered. While Ms. Manley may have given birth to the audacious product, it was conceived by the company's chief hi-fi designer, Mitch Margolis.
