Hey....... just got my amp back after some mods to the system as a whole as well as the caps and I can only say as well as the improved bass I'm hearing things I didn't hear before which surprised me. The caps are very cheap Ansar .47uF used in a lot of better quality audio and the increased capacitance does indeed improve the bass as well as well as quantity of bass. There's more punch, body and better layering. It sounds so much more real, more like you're there so it has plugged the gap that was there before. There's still that fantastic Little Dot sound but even better, more of a speaker type sound. Having said that I think the .47uF is as high as I would go because I don't want the bass to overpower the treble. Thats all on my first hearing so no burn in either. I plan to put some Mundort Supremes in eventually but I'm in no rush, I'm just enjoying it now, goosepimples and all......
