View Full Discussion Simple circuit, Alps pot, $6 OP-Amp, 9V Battery, and a Cinnamon Mint tin=serious power on the go for the HD58X's!
Looks great! Would be a great project, do you have the BOM and schematic? Would love to do something like this for my HD6XX's coming in September.
I purchased mine all assembled, but I did swap out the OP Amp for a better one. It has loads of power with the HD6XX as well.
