The A-S2000 Amplifier is an integrated amp which offers full-stage balanced transmission, combining high power output with good sound texture and outstanding S/N performance The capabilities of the A-S2000 Amplifier will be heard to best effect when paired with the CD-S2000 CD player.
The Yamaha A-S2000 Amplifier achieves fully balanced signal transmission from input to output (balanced design refers to the use of two signal conductors that have equal impedances to ground). The Yamaha AS2000's balanced transmission is capable of cancelling noise produced internally and externally, and so is considered to be an ideal amplification method, eliminating the sound quality degradation caused by noise. If it is only partially adopted, however, it will be largely ineffective and may even have negative effects.
The Floating Balanced Power Amp configuration used in the Yamaha A-S2000 amplifier adopts an output element having identical polarity on the plus and minus sides of the output stage, with both sides having their own power supply and feedback, thereby achieving total symmetry of pullable operation at the output stage. The AS2000's power supply unit has four floating elements (no restrictive grounding connections), two for each channel, so plus and minus are completely symmetrical.
The Yamaha A-S2000 amplifier has four large capacity power supplies for the power amp that are completely isolated from ground. Shunt type local regulators that prevent degradation of sound quality by amperage fluctuation ensure a clean and stable power supply for the preamp. Naturally, parts that directly affect sound quality such as the large power supply transformer and carbon sheath block capacitors were chosen only after careful evaluation.
