Yamaha announced four hi-fi integrated stereo amplifiers, comprised of the A-S301, A-S501, A-S701, and A-S801 (pictured top), priced from $400 to $1000 for budget stereophiles. Each model is crafted with Yamaha’s proprietary ToP-ART (Total Purity Audio Reproduction Technology) concept that places the right and left channels in a symmetrical design for the highest sound quality. All four models have an anti-resonance base, while the top three also have a solid center bar that deters vibration and extraneous noise and distortion.
The top two models in the line also offer CD Direct Amplification that maximizes the signal-to-noise ratio of CD sources for superior listening experiences. Pure Direct mode virtually eliminates signal degradation by enabling the audio signal to travel the shortest possible route—bypassing the buffer amp and the tone, loudness and balance controls—to deliver the purest sound reproduction. Continuously Variable Loudness Control maintains the full tonal range of music, which is especially beneficial at low volume levels.
Each model has digital audio inputs for HDTVs and Blu-ray Disc players that provide dynamic sound to all programming, including sports, movies and concerts. They are also compatible with Yamaha’s optional YBA-11 Bluetooth wireless adapter that enables users to easily stream music from compatible mobile devices and computers.
The A-S801 enables the playback of high-resolution music files via its built-in USB DAC function. In addition, it has a high performance ESS Technology SABRE32 Premier Stereo DAC and double-bottom chassis for the reduction of distortion-causing vibration.
The A-S801 and A-S701 features gold plated terminals for speakers and for all input sources while the A-S501 features gold plated speaker, CD and phono terminals.
The other main specification difference is regarding wattage, which ranges from 60-watt to 100-watt per channel. See full specifications compared.
