23bit 64x over-sampling digital-analog converter with balanced input and enhanced tube output

This is one of our state-of-the-art designed D/A converters having a resolution of 23 bits and 2,822 Khz (44.1Khz x 64= 2.822Mhz) re-sampling frequency that can completely eliminate digital noise from original CD data. Between each original databit, 63 more databits are calculated and inserted to complete the music signal. This serves to bring back an LP smoothness and warmth in the playback. 8 ASP’s (audio signal processors) are installed in this design to recalculate harmonic response up to 70Khz to assure correct reproduction of music (equivalent or better than the best quality MC cartridges).

This unit has been equipped with a true balanced tube output stage to ensure the best dynamics, superb sonic performance is achieved, as well as low output driving impedance.

This super version is an upgrade from the DA-64XT, which also boasts a super enhanced tube buffer stage as well as an XLR balanced input, (which has about a 20%-30% overall improvement in sonic performance compared with the standard DA-64XT version).

A super low output impedance (50ohm) module is also offered as an option to further boost the driving power with an additional cost of $500, one additional pair of XLR’s + RCA’s in a super low output socket will be added.
