Hi all owners of this great Pi dac.

Just a small mod I have done to the output filter on these boards.

The resistor used in the out of band noise low pass filter is a crappy Smt, this can be changed to a quality Charcroft Z foil or Shinkoh with all the benefits using these bring.

I thought about removing it completely, but if you use a class d amp you can run into problems.
