Nice. Do you have any graphs of scope measurements? Or any other "technical" information about this board?

Hi, Here are some of the description of the IC CM6631 from cmedia, I want to upload the datasheet, but it is a bit large with 16 pages and failed to upload here, if someone intrested in it, you can search on google or PM me, I can send to your email box. This is a great IC!

"Cmedia CM6631 is the world’s first USB2.0 true high-speed audio processor that can support the latest USB Audio Device Class Definition V2.0 and high-definition audio processing capability up to 192KHz/32bit. CM6631 provides the industrial standard I2S and HDA audio interface and also integrates 192KHz/24bit S/PDIF transmitter/receiver and MIDI I/O device. It’s suitable for versatile, high-profile, typical 2-channel I/O audio applications. Furthermore, CM6631 has an embedded 8051 microprocessor that can enhance the best flexibility and functionality with external upgradeable F/W codes. CM6631 would be the most high-fidelity and powerful audio core for high-value USB2.0 audio products. "
