JohnW: What is a price for Streamer / DevDAC combo? Does it have galvanic isolation between XMOS and DAC, right?

Just one small warning.. I had to return this DAC, because it does not have a galvanic isolation of USB port and it did not work well in my crazy electric wiring setup. There has been noises from USB data transfers induced into speakers (whistling at 8kHz). I have a desktop PC with an ATX...

OK, thanks for the answer! :-)

JohnW: What will happen with MiniDAC design? Does the other company owns the rights? Or is it possible that you will release it later as populated board for DIY usage? The Internet is full of low-quality DAC boards (and kits) from China, so why not use (or sell?) completed design of a...

JohnW: I just wonder why have you not used a BeagleBone Black for this embedded player. It accepts Master Clock and it has 4 I2S outputs, which could be used for native DSD playback (4 channels). Officialy it supports only 192kHz, but it works well with 384kHz in stereo mode (but no 768kHz)...
