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 word, 511 more data words 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 : 96Khz 24bit

(Note: The upgrade price quote is a special deal for newly order unit only, modification of existing unit will be around C$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 installed with 10 more tubes .

24Bit 192Khz (SPDIF + AESEBU) input + regular USB input upgrade +C$500

24Bit 192Khz (SPDIF + AESEBU) input + 24bit USB input upgrade +C$700

32Bit 384Khz DSD USB input upgrade +C$500

24Bit 192Khz (SPDIF + AESEBU) input + 32 bit DSD USB input upgrade +C$1,000
