Yamaha AS1000 Integrated Amplifier 

High performance amplifier that takes full advantage of the sound quality benefits of balanced amplification.

With the A-S2000 and now the A-S1000,Yamaha has taken the bold step of using a floating balanced configuration to update the power amplifier for serious music fans 

Triple parallel electronic volume and tone controls

By completely isolating the plus and minus sides of the left and right channels of both the NFB and power supplies, the AS1000 achieves perfectly symmetrical operation

Circuits that contribute to the A-S1000s high sound quality are identical to those of the A-S2000

The A-S1000 uses a fully discrete phono equaliser circuit, whose quality is comparable to those in high-end control amps

The AS1000 base is equipped with height adjustable, solid steel feet that maximise stability and thoroughly dampen any external vibration
