I had a fair bit in common with you - ESL63s,Classic 60,SP-9. I was very happy with the change on going to Goertz MI-2.
Best interconnect (pre/power) I used (of many) was Siltech FTM-4. Also Audio Note worked really well(less detail, but maybe more natural). Dont use my turntable much, but got good results from my Sony CD player after doing LCaudio mods. There really is beautiful bass in those Quads(if limited in volume).
