Full Description
“One of the greatest budget loudspeakers ever, the 9.1s deliver a quality-laden performance…the 9.1s also look and feel like far more expensive speakers. Forget the bog-standard box design commonly used for budget boxes – these elegant standmounts boast curved, braced cabinets, cranking aesthetic appeal up a notch, and also helping reduce unwanted cabinet vibrations and dissipate any standing waves produced by the mid/bass driver.”
Yamaha A-S301 Stereo Amplifier
High Sound Quality Circuit Design
ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha’s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid centre bar provide high-rigidity support and vibration damping. These Yamaha design innovations contribute to this amplifiers’ rich audio reproduction with abundant musicality.
Outstanding Audio Performance
Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.
Pure Direct Mode for Greater Sound Purity
Engaging the Pure Direct Switch causes the audio signal to bypass the control circuits for bass and treble, balance and the back buffer amp. This improves sound quality while maintaining full output capacity. Shortening the signal route improves sound purity, helping to reproduce even the most delicate musical nuances.
