Do know when, if, the "Hybrid Output Stage 2" pcb from the "USB DAC 2 - Hi-Resolution System" will be available for sale? Thanks.

Another USB to I2S board that might be interesting to compare is the exD audio, that also has the interesting feature to output LJ24 signals, very useful for a direct connection to the PCM1704 DACs. Do someone have informations on it?

Hello i started to test and translate i2s to TDM but i have no experience but still trying harder.. i red many of papers that how i2s works but no clear small examples for programming on c or c++. first i want to have little example that how to pragramming i2s and want to test my own source of kit based on XMOS with appropriate software.

My kit is USB AUDIO Multi Channel kit. i lost much time i want it step by step but its is too late to do that because i have few weeks to finish my project.

May it stupid questions for you but i couldnt find such a example and software yet. Any one advice or lead me would be appreciated.. thanks
