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.

At a hi-fi show in Germany a few years ago, an audio club had set up a room filled with a dozen well-known turntable/tonearm combos. I recall seeing the Clearaudio/Souther, Immedia RPM-2 and arm, VPI TNT Mk.IV/JMW Memorial, Basis 2500/Graham 2.0, Oracle/Graham, Linn LP12/Ittok, SME Model 20/SME V, and some others I can't remember, including a few not exported from Germany.

It's not every Consumer Electronics Show that someone introduces a $29,000 solid-state phono preamplifier—and I miss it. The 2002 CES was one. My show report in the April issue made it seem as if I'd found out about it there, but the fact is, someone clued me in after I'd returned home. I needed to come clean on that.

I've been meaning to review this Tim de Paravicini design for years. Finally, egged on by readers, here goes.
