The Yamaha A-S1000 is a hi-fi natural sound stereo amplifer falling near the top of those offered by Yamaha. This system uses a new, superior approach to analog amplifier design and inherits the high sound quality design of the flagship A-S2000 to bring out the best of other components in your system. Some notable features include triple parallel electronic volume and tone controls and a fully discrete phono equalizer and MC head amp.  It is designed using symmetrical construction and has specially designed feet.
