Yamaha A-S2000SL overview

  • 1Description

The silver A-S2000 Natural Sound Stereo Amplifier from Yamaha boasts a power output of 90W x 2 (RMS) and uses high quality components and construction to provide fine acoustic performance. The A-S2000 achieves fully balanced signal transmission from input to output. Balanced transmission is capable of canceling internally and external noise, and for this reason, is considered to be an ideal amplification method. The A-S2000 offers full-stage balanced transmission, combining high-power output with excellent sound texture and outstanding S/N performance.

The A-S2000 features four large capacity power supplies for the power amp, and is completely isolated from ground. Shunt-type local regulators that prevent degradation of sound quality by amperage fluctuation establish a clean and stable power supply for the preamp. An extremely low-noise phono preamp and dedicated MC step-up circuit are responsible for musical clarity and imaging with both MC and MM phono cartridges. A fully discrete, high-performance headphone amp performs admirably with even the most cutting-edge audiophile 'phones.

Completely symmetrical construction offers the ultimate in integrated amp left-right separation, a central reinforcing bar provides rigidity and stability, and specially designed height-adjustable feet allow listeners a choice of two bases.
