Review from customer :

Our DAC (Digital-to-Analog Converter) incorporates a powerful 8x TUBE up-sampling processing unit, which surpasses solid-state or FPGA up-sampling circuits by eliminating at least 1000 transistors. This advanced technology ensures superior sound quality, even surpassing most vinyl analog playback.

With the TUBE up-sampling unit, a standard CD quality input of 44.1Khz automatically up-samples to 352.8Khz. When using higher resolution files such as 96Khz or 192Khz, they are up-sampled to 768Khz or 1,536Khz resolution, respectively.

The up-sampling process is carried out by an array of tubes, enabling real-time updates for each sampling delay. To achieve this, a recursive infinite taps butterfly summing unit, originally used in neural networks, is employed. This unit provides even better sonic performance compared to a million taps FPGA up-sampling filter processing. The results are exceptional, ensuring a remarkable audio experience for our customers.

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 16 triode 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 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, this is simply the best analog sounding DAC of the year. USB input capability let you easily hook up your music server / MAC / PC or smartphone with supported USB audio interface. S/PDIF coaxial digital input for regular CD/DVD player or any device with optical / SPDIF output. We strongly believe this unit can easily take down any other name brands DAC even over $60,000 range. Real time data stream sampling frequency measurement and display, can show stability (jitter level) of input data which no others did. Solid thick aluminum chassis.

Our DAC excels in performance with DSD64 input, which is up-sampled 8 times to DSD512. Similarly, DSD128, DSD256, and DSD512 inputs are up-sampled to DSD1024 quality, ensuring exceptional audio reproduction.

Featuring a specially designed 16 triode tube section, this DAC effortlessly transforms digital sound into high-end vinyl MC cartridge-like playback quality, exhibiting remarkable micro and macro dynamics with an impressively low noise floor.

Compared to other major brands in the industry, regardless of their extravagant pricing or cutting-edge technology claims, our DAC outperforms them all, delivering the best analog-sounding experience of the year.

With USB input capability, it conveniently connects to music servers, MACs, PCs, or smartphones using supported USB audio interfaces. Additionally, the S/PDIF coaxial digital input allows compatibility with regular CD/DVD players or devices with optical/SPDIF output.

We firmly believe this unit can outperform any other name-brand DAC, even those priced over $60,000.

Moreover, it provides real-time data stream sampling frequency measurement and display, offering insight into the stability (jitter level) of the input data, a feature not found in other DACs.

Our DAC is meticulously designed with a solid thick aluminum chassis and solid-oak side panels, guaranteeing robustness and long-lasting performance while exuding an elegant and timeless appearance. Moreover, the combination of these materials contributes to a natural tonal sound quality, elevating your audio experience to new heights.
