This is one of our state-of-the-art designed D/A converters having a resolution of 26 bits and 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.
128 ASP (audio signal processors) are installed in this design to recalculate harmonic response up to 70Khz to assure correct reproduction of music in one single pass of algorithm (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 for RCA signal. XLR output drive any input >10Kohm, optional super low output impedance 50ohm drive addon possible with additional cost.
This DAC compose of 3 separate units. Here is the signal flow. First the CD coaxial / balanced input enters into the "digital interface" unit, then the pre-processed data enters the second "128 ASP" unit, the output then becomes a perfect analog signal, it then enters the final tube buffer stage. From the buffer stage output you have a superb sound so perfect it heavenly. Even LP are hard pressed to compete with this superlative rendition.
Max.digital input frequency : 96Khz 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.
