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! 73, David KB4FXC
