SANSUI AU-555 STEREO INTEGRATED AMPLIFIER * JAPAN *
Description : 02 Jun, 2023
MAJOR CLASSIC, NICE, SUPER CLEAN, ALL ORIGINAL NEVER REPAIRED, FULLY SERVICED, WORKS AND SOUNDS LIKE NEW
The Sansui triple digit series stand apart from the rest. The build quality is as good as it gets, regardless of price tag, old or new, see the pictures
The circuit of AU-555 mimics a tube amp, but with solid state transistors in place of tubes. The sound is similar to a high quality tube amplifier, without all the tube hassles. The sound quality is similar to that of Marantz 1060, however I feel the Sansui wins in overall warmth and smoothness.
This AU-555 will be tested for local Ottawa area buyer at the front door with CD player, turntable and speakers. Can be shipped in Canada, keep reading.
