Sony just announced the TA-A1ES integrated stereo amplifier, which utilizes a frame/beam/base chassis that was originally developed for Sony’s acclaimed R-Series components. It delivers crisp, noiseless power performance. Employing FET input and buffer circuits that enhance performance, the amplifier’s optimum gain volume control combines electronic volume with a discrete buffer amplifier, allowing it to massively reduce gain error and produce sound quality superior to conventional volume controls.
The TA-A1ES has a power amp stage featuring Smart Bias Control for Class-A operation and Single Push-Pull Hi-Current Amplifier. It is designed with a single pair of transistors to eliminate variations in each channel at the source, as well as variation controlling emitter resistance, allowing the transistors to drive the speakers directly, for a more character-free sound quality. Sony’s proprietary toroidal transformer packs a 300VA rating, the highest in its class, as well as a capacitor delivering 24000μF per channel.
The TA-A1ES is part of Sony’s Elevated Standard Series and has been specifically designed to complement the company’s new HAP-Z1ES reference standard Hi-Res Music Player.
