Technical aspects

An oversized power supply producing a DC signal with a noise floor of -140dB related to 1.0V, DC-100kHz
Power supply voltage regulation includes i²DCf (Independent 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; 24 stages in all
Selectable equalization curves for both the RIAA and the IEC standards
Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%
4-Layer printed circuit boards with pure copper tracings for a much shorter signal path;
This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
Power supply featuring a “pi-type” filter comprised of 40,000uF of capacitance and dual choke inductance
12 Volt trigger input and output for remote operation
Ultra rigid chassis construction to minimize the effects of external vibrations
Accurate matching of the very finest quality electronic components in a symmetrical circuit design
