The amplifier design technology from Yamaha is called ToP–ART which features an input to output with a direct symmetrical design. ToP–ART design and ART Base ensure optimum sound when processing and transmitting the audio signal. The signal is simple and direct, therefore it is less likely to be affected by noise and distortion. The left and right channels are organized in a straight, symmetrical layout for the highest signal purity. In addition, the ART (Anti–Resonance and Tough) Base bottom chassis and a solid center bar provide high rigidity support and dampers vibration. These design innovations contribute to this amplifier's rich audio reproduction with abundant musicality.

Notice the custom made power transformer, custom made block capacitors, two direct signal path speaker relays, one point grounding system, extruded aluminum heat sinks and other top quality parts to effortlessly handle demanding audio conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of this component. Yamaha uses only very high quality parts, carefully selected and tested for their sound properties.

The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp, the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.

With a beautiful, simple and unique design inherited directly from Yamaha Hi–Fi audio components, this amplifier also boasts an easy to operate layout. The aluminum front panel has a richly textured silver hairline finish. The control knobs are also of the same luxurious construction as used on our top end models.
