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

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 databit, 511 more databits are calculated and inserted to complete the music signal which serves to bring back an LP smoothness and warmth in music.  Due to the high up-sampling rate, there is no need to put any analog filter circuitry in to kill digital noise, so no phase shift or harmonics are lost in the high frequency range, this results in the best layers of air in music reproduction. The sonic hologram is of such high density and seems so natural that you can hardly experience this with any other brand of DAC.

32 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.

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

The 5U4G 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.

(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.
