OCTAL Core 8x up-sampling DSD DAC (max. up-sample to DSD1024 or PCM 32bit 2,822Khz)

USB input can take 16-32 bit 44.1K-384Khz PCM & native / DoP DSD64, DSD128. DSD256 and DSD512

S/PDIF coaxial / Optical input can take 16- 24bit 44.1K-192 Khz PCM data

with RCA+XLR analog output, 6550 x 2 power tube and 274B tube rectification (KT120/KT150/EL32 ready)

default tubes: 6550 x 2 + 274B

(option:KT66/KT77/KT88/KT99/KT100/KT120/KT150/EL34/5881/6CA7/6L6/6G6/6Y6/6K6/ well as EL32 / CV1052..... and all those compatible tubes)

(Rectifier option: 5AR4, 5U4G, 5R4, 80, 180, 280, STR-104, STR-1001, STR-1002.... and all compatibles, with 4 pin > 8 pin adapter can use 83, 300B, 2A3 (set to 2.5V)...and all their compatibles)

With our powerful octal core hardware up-sampling processing unit (similar to use FPGA but with a better solid fixed logic modules) in this DAC, regular CD quality 44.1Khz input can automatically up-sample to 352.8Khz, if use higher resolution files such as 96Khz or 192Khz, they will up-sample to 768Khz or 1,536Khz resolution. The process is carry by an array of ASPs, which perform real-time update for every single sampling delay, a recursive infinite taps butterfly summing unit (originally used in neural networks, functionally equivalent to but with even better sonic performance than use million taps FPGA up-sampling filter processing) will adds up each mulitipliers result and feed to the next coefficient for next sample processing.

DSD64 input will be 8x up-sampled to DSD512, and DSD128, DSD256, DSD512 input will up-sample to DSD1024 quality.

Combined with our special designed organic pure tube rectifer and big output tube section, easily convert the digital sound into analoge alike high-end vinyl MC cartridge playback quality, but with even better micro and macro dynamics with super low noise floor.

This might be the one of the best sounding DAC which can work with big power tubes like

KT66, KT88, KT129, KT150, 6550, EL34....etc. This model even include extra terminal for Mullard EL32 / CV1052 NOS tubes.

Rectifier tube use 274B as default, and can use tons of alternation replacement tubes as well.

This DAC can effortlessly surpass the sonic performance of any other DAC offer by major brands in the industry, no matter how crazy unreasonable price they asked for, or whatever mind scrambling technology was quoted.

USB input capability let you easily hook up your music server / MAC / PC or smartphone with supported USB audio interface.

Super enhanced power transformer for "Hanging-in-the-air" 3D imaging, and good enough to power up the power hungry KT120 or KT150 output tubes, which built with pure class A single-ended triode configuration.

S/PDIF coaxial digital input for regular CD/DVD player or any device with optical / SPDIF output.

Super hi-power transformer, point-to-point and component-to-component hand-wired for the very powerful tube section, NOS oil capacitor + Western Electric cloth wiring upgraded, in order to achieve super high performance with such a bang-for-buck price tag, we strongly believe this unit can easily take down any other name brands DAC even over $30,000 range.

Real time data stream sampling frequency measurement and display, can show stability (jitter level) of input data which no others did.

Enhancement over the regular version:

1. oil coupling caps add-on upgrade
2. WE silk cloth wire for internal power distribution upgrade
3. enhanced RCA socket upgrade
4. NOS carbon composite resistors upgrade for tubes section
5. ultra thick black aluminum chassis
6. level-1 low output impedance upgrade
7. 100 step IR + BT remote volume control with balanced knob
