My initial impression after the mod is that there was a noticeable difference in overall sound but didnt even come close to sounding like Jerry's. The bass and mid-bass on his was substantially better IMO. At least I know what I have to look forward too. Jerry has a nice set-up. I think tubes might be in my future to some degree.
Word of mouth is that doing the rings is probably the most drastic improvement. Can't wait for them to get here. So in the mean time, they can just burn in. Hopefully in a week, everything will be done, the speakers spiked and I can get a long with the show.
I just want to give a shout out to both George and Jerry for their help on the crossovers. They did an excellent job and the crossovers looks really nice. I will post some before and after pics one I find the charger for my camera.
