I feel like this Amp is just so close to perfection but there’s just something missing. I have two ybas and they just have a bit more snap sizzle and bite. The only thing I did to them was change the volume pots because the treble freq was just a tad trebly and the mod worked well. However with the ysr it’s a little different. It’s a little more damp and dark sounding. Has anyone ever made these sound a little more like the YBAs? Any suggestions? I guess it having original filter caps would be an issue but it’s still loud and reliable plus they are welded in. I feel like there is a treble cap missing somewhere.
