ProtoDAC TDA1387 X8 project

[wolf7250]

Nelson Pass often uses SMPS for his preamp designs. He triple filters with simple RC filters. I have also seen him use LM317 (60dB ripple rejection) linear regulators at the end. The SMPS DC Filter P089ZB Kit and the other filter posted by @wolf7250 specifically filter noise typically generated by SMPS. These techniques may be enough to adequtely filter noise, and provide continuous power.

I'm going to give the diyAudio SMPS DC Filter P089ZB Kit a go. Have ordered it and will give it a crack.
Haven't done much soldering... between this kit and the ProtoDAC I'll probably have a bit more experience. Looking forward to learning. I will be watching YouTube tutorials etc before beginning   .

Thanks @hifinet for all the information and advice!
