Here is the status: I had it playing music almost two weeks ago, but there were issues, such as not following sample rate changes properly and not starting when the FPGA filter was turned on. I have been working like crazy on these and have them all fixed, but somewhere along the line I broke something and have a strange corner case. If the DAC is on and you plug in an S/PDIF cable from a transport that is already sending out data anywhere from 2-5 minutes later the output gets highly distorted for about 5 seconds, then everything is fine from then on.
This is tough to debug since it happens randomly, but often enough to be not good. I want to get this fixed before I release it. I'm going to be working on this full time for the next couple days and hope to get it fixed. (and not break anything else!)
The final thing is to get the new filter encoded into the DAC, this takes a good part of a day, so I hope I can get the above problem fixed soon so I can get filter added and get this to Doc next week.
Even with the old filter it sounds fantastic, but with the new filter (running it on a computer to try it out) it's really amazing.
