While on the topic of USB soundcards....

Has anyone played with one of these boards??

See: http://www.ebay.com/itm/171883307218

I'm not seeing any audio input pads on it, since it's targeted as an
output device. But, I like the I2S DAC (which includes DSP alias
filtering, I think?), dedicated headphone amp and non-potted CM108! This
should provide a stellar output audio S/N--something that is sometimes
lacking in the el-cheapo cards. Oh, and a decent price, too!
