This year we introduce an especially impressive model: a new high-end stereo amplifier, the A-S2000. Putting you in the same room as the musician. Hear the full potential of your music - Yamaha HiFi. The A-S2000 achieves fully balanced signal transmission from input to output. Balanced transmission is capable of canceling noise produced internally and externally, and so is considered to be an ideal amplification method, eliminating the sound quality degradation caused by noise. Its capabilities will be heard to best effect when paired with the CD-S2000 SA-CD/CD player, which employs the same principle. The Floating Balanced Power Amp 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 feed back, thereby achieving total symmetry of pull-able operation at the output stage The power supply unit has four floating elements (no restrictive grounding connections), two for each channel, so plus and minus and completely symmetrical. To achieve fully balanced transmission, all audio circuits except the phono equalizer and the headphone amp are balanced. The line amp also uses a balanced configuration for its volume and tone circuits, achieving fully balanced transmission form the XLR balanced input jack to just before the speaker jack. Additionally, the output from the unbalanced RCA input and phono equalizer undergoes balance conversion internally. The A-S2000 has four large capacitor 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. Large heat sink, huge power transformer, custom-made block capacitors (24,000μF) and preamp board. Also, the A-S2000 has a completely symmetrical construction intended to achieve the ultimate in integrated amp left-right separation, equal to that of separate amps. A central reinforcing bar ensures that the chassis is rigid and stable.
