Hi,
So I spent this morning putting together a headphone amp with 2520. It works but doesn't sound right to my ears. I believe that it lacks bottom end and highs are too bright. I'll post schematic and some pics in the evening, but I followed a standard API312 schematic without transformers and added 1M resistor from +IN to ground. Powered with +-15V
any ideas how to improve it? or it is just 2520 sound?
ps. I didn't use any caps except of 330uF
pps. here's schematic from classicapi site, just for now so that we all know what we are talking about:
