ProtoDAC TDA1387 X8 project

[Skip Pack]

ProtoDAC can only handle 5V (5.5V max). You can use an LT1963 module to regulate down to 5V. The one problem with the LiPO is the higher ESR (internal resistance) compared to LifePO4 batteries. The LiPO don't sound as dynamic.

The Soviet K77-1 polycarbonate caps sound excellent. Just trying them now. Great value. Sound better than the used CRC 10uF 30V.

I use the LiitoKala Lii-202 .

Hi, I have just picked up a pair of those Soviet caps, do they take awhile to break in?
cheers

Longtime general Soviet cap reputation says yes. These are the first Soviet polycarbonate caps I've used. I just use MoOde's  repeat play with a huge directory of album subdirectories, and the amplification chain off.
