@sns good feedback so far on what seems atypical of the burning process. keep us updated. I am still not sure if I want to upgrade to 006 - so many DACs available at this price range. On one side I kept thinking of trying a non-Sabre DAC - AKM, R2R, Fpga, Hybrids, but then the Musetec 005 also sounds very musical in my setup. Not sure what to do - a problem with too many choices :-)
@melm nice summarizing all the types of DDCs.
There is one DDC that called my attention - its a Audiobyte Super Hub. Its expensive compared to others but I have heard good things about it.

With my experience with digital and a lot of DIY along the way, it extremely difficult to pick a winner. There are so many factors with digital that affects the sound, it is hard to say in advance what will work in one’s system. One really got to try it out. However, one thing that I can say confidently and which has worked in every situation is the better and more stable a power supply, the better the sound in digital.
