I use to own a SP-6A, SP-6B.ARC had other mods done on them with ARC SP-6C, 6E, i BELEIVE AS WELL.I had heard that a rare SP-6F was made which is actually a SP-8 in a SP-6 outer shell. The amps of the day that worked well with the SP-6 were the ARC D90B. I used a Hafler DH 200
Solid State Amp when I had the arc preamp, and a Ram Labs Head AMP for additional gain in the phono stage and all had it hooked up to Acoustat ELS SPEAKERS.Boy does that bring back memories.
