Vinyl playback of exceptional clarity
Don’t simply connect a turntable, honor it with a phono preamp stage of uncommon quality. Ready for both Moving Magnet and Moving Coil cartridges, the SpinStage™ phono preamp delivers a host of circuitry refinements and a range of adjustments that would make some expensive preamplifiers jealous. No wonder Ian White of eCoustics named it an Editor’s Choice.
Exactly the right impedance
Although phono inputs are gaining popularity, not all audio systems have them. Of those that do, only a few accommodate low-output Moving Coil (MC) cartridges as well as Moving Magnet (MM). And only a very few have the robust input impedance options to exactly match the needs of your particular MM cartridge. The SpinStage preamp provides four separate MM input impedance settings, and a staggering 15 separate MM capacitance options. You’re not simply connecting a turntable; you’re eliciting its full performance.
True Moving-Coil gain stage
Low-output Moving Coil cartridges are highly-prized by audiophiles. But most value-priced phono preamps accommodate MC cartridges by simply increasing the gain on their Moving Magnet inputs, an approach that increases background noise. In dramatic contrast, the SpinStage preamp incorporates a dedicated Moving Coil gain stage. So, you’ll hear true Moving Coil performance – against a background of satisfying silence.
Highly refined circuitry
As the lowest-level signals among component interconnects, the magnetic cartridge outputs are exquisitely sensitive to even tiny amounts of noise and distortion. The SpinStage preamp protects your music with isolated dual-mono circuitry, a DC servo circuit and a switchable subsonic filter (20 Hz, 12 dB/octave) to keep turntable rumble under control.
