ProtoDAC TDA1387 X8 project

[hifinet]

Hi Mark, hi everybody, 
This is not related to the component shortage: I wish to informe you that I have seen a version of "parallel TDA1387" made with 4 IC only, but with discrete components instead of SMD components. I am trying  to buy a couple of them (to be wired in parallel) to test if those capacitors "sound" better. At the moment I have not been lucky finding them: may be that your chinese supplier knows how to find them, or somebody else, in the forum, can help in this way.
Best regards and thanks,
Francesco

I bought one years ago. I never used it. Still have one. I have not seen them for sale in quite a while.

Changing the SMD caps on the X8 module is well beyond my capabilities, but they do make film acrylic SMD 1uF caps in 1206 and 1210 sizes. Even those seem too big.

Another thing to try is to eliminate the 1uF pin 7 caps entirely by just clipping them off (the larger C2, C4, etc). Abraxalito omits the cap on his TDA1387 designs.

The other caps are the 100nF power supply decoupling caps, and MLCC are supposed to be optimal for that application.
