Music nuts lust after spatial sound: output so precise you can pinpoint each instrument’s location in the recording hall. Well, the room-size Model C isn’t just spatial, it’s intergalactic. We dare you to listen to this integrated CD player, amplifier, and speaker symphony without jumping up to conduct. While most speakers are sealed boxes, Steinway’s engineers left these open, replicating the resonance of live instruments. And unlike other systems, which convert the audio signal from digital to analog in the amp — many sound-distorting circuits and wires away from the speakers — the C is digital from source to driver. What comes out is as close as you can get to what went in; in fact, it’s so pure that experts can discern a violin’s make and country of origin. The only weak link in this six-figure aural experience might be your musical taste. So lose the Coldplay, moneybags.
