Some people have run a QB-9 with the Touch without any problems at all. So there has to be something DAC specific, Touch hardware specific or configuration specific.
What I would like people to try is different sample rates say 44.1 VS 48 or 88.2 and 96. That should wind up exercising different crystals in the DAC. With a USB interface the rate data is sent to the DAC is NOT determined by the audio crystals but by the processor crystal which may not be given as much care in initial frequency accuracy. The result is that the data rate might be fairly far off from what it should be and the feedback loop in the asynchronous interface may not have enough time to get the computer sending the data at the right rate before the buffer over/under flows. I've been working with some others with async hardware and seeing some very strange things happening. The feedback loop IS working but sometimes the data rate gets set to something very bizarre. Unfortunately I can't get any of this to happen on my Touch so its hard to debug.
