Well, I would say the SY-DAP2002 and the mono cards are not playing in the same league at all. The SY is not bad relative to his price. If I autorise myself for audiophile poetry (please excuse me in advance) I can try to write about the subjective differences I was feeling. The SY in comparison to the two mono cards lacks of dynamic, the medium and highs are not "clean", lacks of definition. We push the cursor clearly high with the mono cards where the SY cannot go because power difference and it still was clean.
Interesting fact, using a lab power supply, I started at 30V for the mono cards but they were clipping abit early (clipping LED was blinking) but going to 48V, no more clipping and clean loud sound: we were using a pair of Eleac BDR62 and they like lot of power.
I really would like to see a brother of the SY-DAP2002 without internal ADC and DAC to only have a pure TPA3255.
Another point, I think the option to program something in the SY is too complex at the time we can do something in the player with softwares like REW, APO or Daphile: these softwares have community and plenty of help is available. Maybe I am wrong and the development IDE is easy to learn ? But in the other side, I like to do some things with open source softwares and I do not like the licences (maybe I did not read enough on the subject).
I will add I am not a reference in any subject, I just explain my feelings, I have the right to have some feelings, but they are mine and they are not important.
