Usually I build my presets during night, so most of the time I find myself using Headphones, so as far as I put a Stereo Block at the end of the chain, the sound reaching my ears is wonderful, deep, with no harshness or noises. But if I put a mono block and make the whole path mono, it starts to sound awful, and not "clean" and smooth anymore. What's the best choice to make it sound better? leave it Stereo in headphones? I'm also wondering how it would sound in a Mono FRFR speaker.... I'm puzzled....
