23bit 64x 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 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 data word, 63 more data words 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 . input frequency : 96Khz 24bit in PCM format

Mullard NOS EL32(CV1052/VT52) upgrade add C$250 -- further enhancement in openness, smoothness and silkiness as well as musicality

The 6x5 tube rectifier can further upgrade by our super rectifier STR-104 or higher models , direct plug and play without any mod required.

With this super rectifier adaptor, you can use 300B, 2A3 , 45 , 50 , 80, 83, 1616 , 3B28 or 866A as rectifier tubes option.

No. of inputs 1 set of coaxial digital  inputs  
No. of outputs 1 set of RCA outputs + 1 set of balanced outputs
Freq response 10Hz - 70Khz (-3db)
dynamic range better than 110 db
Max. output volt 2V rms
Phase non-inverted
manufacturing hand-wired point to point for tube section
Tubes used 2 x 6G6G + 6X5 rectifier (optional :  5U4G rectifier)

(Note: The following 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 with 10 times tubes being used.

Additional Upgrade :

add 5U4G rectifier with bigger power transformer (+C$200)

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

1 year parts and labor warranty, tubes 90 days under normal operation condition
standard chassis : Gold/ Black/Metallic MDF , Aluminum chassis

(optional chassis : Mirror steel, black piano , solid-oak )
