Spectral’s DMC-30SS is a tour de force in preamplifier design, with its ultra-fast circuits, heroic volume control, innovative power supply, and meticulous attention to detail. Putting it into a system is like washing months of winter off a picture window. Timbres are richly saturated, soundstages huge and defined, and resolution of transient detail is superb (provided that these qualities exist in the recording). Moreover, the DMC-30SS has absolutely spectacular soundstaging, with tremendous depth, width, layering along a continuum, and sense of air among instruments. The DMC-30SS is extremely “fast”-sounding with lightning-quick reproduction of transient detail, yet it never sounds analytical. A world-class preamp that is underpriced relative to its performance. spectralaudio.com
