The Yamaha A-S300 Integrated Amplifier is a beautifully crafted entry-level hi-fi amplifier that offers exceptional audio performance, quality construction, and thoughtful features. Built with Yamaha’s ToP-ART (Total Purity Audio Reproduction Technology) and symmetrical circuit layout, this amplifier ensures a clean signal path and dynamic, transparent sound across a wide frequency range.
Delivering 60 watts per channel into 8 ohms, with the ability to handle complex speaker loads, the A-S300 is ideal for both casual and discerning listeners. Its elegant aluminum front panel houses tone controls, balance adjustment, a loudness dial, and Yamaha’s Pure Direct mode, which bypasses tone circuitry for the cleanest possible signal path — perfect for audiophile-grade playback.
It features six RCA inputs including a dedicated MM phono input, making it ready for turntables right out of the box. There’s also a subwoofer output, record out, and dual speaker terminals (A/B switching) for added flexibility. The amp includes a remote control and an energy-saving auto-standby function that powers the unit down after six hours of inactivity.
With its clean, powerful sound and premium finish, the Yamaha A-S300 is a solid foundation for any two-channel stereo system.
