An oversized power supply · 3 stages of DC voltage regulation · An exceptionally short signal path measuring only 10 inches in length from the rear panel's input to output connectors, yielding a much faster transient response · Open loop zero feedback circuit topology using absolutely no capacitors anywhere in the audio signal path · Power supply voltage regulation includes Evolution series i²DCf (Independant Inductive DC Filtering); There is one inductor dedicated to each integrated circuit type component (DAC, Op-Amp, etc.) in the audio circuit’s signal path - 14 stages in all · J-FET input devices · One single-ended audio input, of your choice, which functions as a “pass-through”, bypassing the gain stage to accommodate a component such as a home-theater processor, whose own volume control is used instead · Accurate matching of the very finest high quality electronic components · IR input for external control (all discrete codes) · A symmetrical circuit design · Four-layer PCB tracings; The advantages include better ground and power supply circuit layouts resulting in a much shorter signal path and dramatically improved signal-to-noise ratio · Pure copper circuit board tracings with extremely low impedance characteristics · Extremely rigid chassis construction to minimize the effects of external vibrations · Improved reliabilty through the elimination of moving parts · Designed to be powered up at all times for optimal performance · Low operating temperature for a longer than normal life expectancy.
