Hi, all

I decided to go ahead with my $300 experiment by "adding more boxes" between Airport Express and my DSP, and here are useful findings, followed by some questions.

After adding the DDC (linked in previous reply), the sound improvement was instantly noticeable. The sound is much thicker, and refined, felt like I was listening to different music. This would be probably because DDC's main purpose is to reduce the jitter which I believe Airport Express produces plenty. Up-sampling also works just fine, and x2 gives 88.2Khz which triggers beautiful amber light in my DSPs. Overall very satisfied, and decided to keep it in my system, but here comes the biggest problem.

I hear very frequent disconnect(skip, click) in sound (about 0.1 sec), which sounds like there could be some sync issue. This is obviously something I don't want, despite there are lot to gain in the SQ. Can experts share their insights on why this would be the case. (It is also same when I use "pass" mode which outputs 44.1Khz) However, during the 88.2Khz output the amber light in DSP does not blink, which should mean that the incoming signal is "locked"

The technical specifics that I am aware of so far, regarding this DDC is that the optical input uses "asynchronous transmission." to deliver best possible audio quality. Would changing it to synchronous transmission resolve this issue?

Thank You in advance.
