Stereo Box RS is an audiophile-grade integrated amplifier that strictly follows our ‘less is more’ principle in the analog circuitry. All analog, it offers 6 line-level analog inputs with dual-mono paths (5x RCA, 1x XLR). It can be used as integrated amplifier or as line preamplifier with an additional subwoofer output option (fixed & variable outs). Pure analogue circuitry with low-noise buffer input stages offers uncompromised audiophile playback. Elegant controls on the faceplate as well as on the included remote foster ease-of-use. The massive aluminum/steel enclosure is both sleek and effectively protects against interference.
