Sansui AU-D55X
Integrated Amplifier
Sansui AU-D55X
Sansui Super Feedforward technology provides clean, low-distortion sound at all power levels. Specifications, particularly those for phono (an amazingly wide frequency response from 20Hz to 100kHz, +0.2dB, -0.5dB, for instance), are on a par with top-of-the-line models from other makers. Super Feedforward DC power amp. Dual-Bridge Rectifier circuit and toroidal power transformer for excellent power regulation. Fluorescent peak power meter. Phono equalizer for moving-magnet and moving-coil cartridges. Independent tape-record selector. Weight 7.7kg.
