A-S1000 Natural Sound Stereo Amplifier

Yamaha introduces a new, superior approach to analog amplifier design. This high performance amplifier inherits the high sound quality design of the A-S2000 and brings out the best of other components in the system.

Yamaha's involvement with and passion for music goes back more than a century, to when they built their first reed organ in 1887. Now they are the world's leading producer of pianos and other musical instruments, and are involved with music in many other ways as well. They manufacture professional recording equipment, they design concert halls and they assist artists at concerts with set up and sound tuning. This knowledge and experience benefits their production of audio components in many ways. They introduced their first HiFi (High Fidelity) turntable in 1954, becoming the first company to actually use the term HiFi. Thereafter they were one of the first to offer mass-produced, high quality audio equipment, and introduced many legendary stereo components. They hope you enjoy the genuine HiFi experience of Yamaha Natural Sound.

  1. 5.0 out of 5 stars

    shaky start but excellent outcome

    Although UPS destroyed an amp. on delivery first time around WWStereo were really thorough in following up and ensuring a replacement was provided with minimal hassle. They are easy to deal with and very efficient helpful and totally genuine about it all. I live out in the boonies and will use them for all my hi-fi purchases from here on in.
