The **Yamaha A-S2000** is a hi-fi natural sound stereo amplifer and is the flagship model of those offered by Yamaha. This system uses a new, superior approach to analog amplifier design with a full floating and balance circuit design including a floating balanced power amp and fully balanced control amp. Some notable features include parallel volume and tone controls, a discrete phono amp and a headphone amp for low impedance drive. It is designed using symmetrical construction and has specially designed feet. The Yamaha A-S2000 is available in black as the A-S2000BL and in silver as the A-S2000SL and comes with a remote.

This ''product review'' has it all backwards. The Yamaha AS2000 is a screaming bargain worthy of three times the asking price. Just LISTEN to it, one short audition will suffice. Absolutely superb.
