For windows a driver is needed. With proper driver it works very well and sound quality is very good to excellent. With MacOs it need no driver at all.

Default Buffalo IIISE with Ian's FIFO and Luckit WaveIO

Just finished my DAC. As Luckit WaveIO supports two simultaneous outputs, SPDIF and IS, and Buffalo DAC supports to switch between two inputs, also SPDIF and IS, I managed to be able to switch between Buffalo onboard Clock (and SPDIF) - and Ian's FIFO Clock (and IS). Interesting comparison! Furthermore I realized to switch onboard clock between mains/ shunt regulator supply - and battery LiFePO4 supply, indeed an improvement with the latter. FIFO dual XO board is always fed with battery LiFePO4.

DAC is based on the PMD100, the two PCM1702, two 6S4P-EV for I / V stage and two 6S4P-EV for the output buffer

Have Build PCM2DSD which convert PCM to DSD,and DSD signal pass 8TAP FIR filter to convert to analog. There are 4 74x574 cihp which could be cheaper than DAC。

looks nice, did you make those boards yourself? I have a bunch of copper clad but I wouldn't even know how to make something that looks remotely as good.

Hi guys, I'm on the forum a few days. I want to share hot news. Photo on my DAC. His appearance is not impressive. But, it applied a new technical solution. Allowing chip RSM1794A, double as a voltage amplifier. For example, 0 dB - 20 volts at the output. The connection galvanic. This solution has been sought by the Eurasian Patent Office. 201300368 priority number from 08 - 04 - 2013. Examination has already been passed. Analogues prejudicial solutions found. In the summer I'll introduce you with this technical solution. In the meantime, I would like to discuss with you the prospects for this DAC.
