26bit 512x over-sampling digital-analog converter with tube output

This is one of our state-of-the-art designed D/A converters having a resolution of 26 bits and a 22,580 Khz (44.1Khz x 512= 22.58Mhz) re-sampling frequency that can completely eliminate digital noise from original CD data. Between each original data, 511 more databits are calculated and inserted to complete the music signal which serves to bring back an LP smoothness and warmth in music. 

32 ASP (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.

Max.digital input frequency : 48Khz 24bit in PCM format

(Note: The price quoted is a special deal for newly order unit only, modification of existing unit will be around $300 higher than the following prices due to more works for disassemble of the original circuits)

Level 1 upgrade : (+ C$200)

Special designed "Super-Drive" circuit, output impedance lowered to 200ohm (can drive any input from 600ohm up to infinity) with better bass control and punch , better definition and improved in overall tonal quality. By adding this upgrade, it sounds like the output with 10 times tubes being used. With this level of upgrade, just add $50 and you can have a headphone output with enough power and current to drive your headphone directly.
