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.

As you read this, are you listening to your stereo? Whatever the music, what you're actually hearing is your public utility's AC as modulated by your power amplifier. No matter how good the gear, the final result can be only as pure as the power feeding your components. Unfortunately, plenty of sonic schmutz usually comes along for the ride.

Our conservative two-channel audio world doesn't easily accept change. Not that many years ago, even remote control was considered a sign of electronic moral decay certain to degrade sound quality. Today, home theater–like operating systems, with their fluorescent-screen hells and microprocessor-controlled functionality are commonplace, even in the highest of fi. Consumers accustomed to the convenience of audio/video processors now demand it on every price tier of two-channel hi-fi, though purists who think sound quality is commensurate with inconvenience can have that if they want it.

What a thankless task! No, not reviewing audio equipment (though the case could be made). I'm talking about preamplification in the digital age: who needs it? The EAD DSP 9000 MK3 digital processor I'm using includes an ingenious full-resolution digital-domain volume control accessible by remote control.
