1) Caig Pro Gold on all of your contacts.
2) Room treatment, the other most important component.
Tboooe,This morning I had my neighbor(a jack of all trades)evaluate my house for dedicated lines.His response was "a big job with costly repairs".So a regenerator is on list.
In the past i've used two RGPC 400,I sold them and bought a BPT2 with Auricaps,Z sleeves etc.Although I felt the BPT to be better then the 400's.I was not satisfied with the BPT in the long run.
Have you auditioned any other Re-gen's beside the PS audio.I have SET amps and listen to analog only and seem to be stuck with my standard 15 amp outlets.
The early R&B you mention,would that be the Moonglows,Harptones and the like.
I appreciate yours and the members input

Dodgealum Thanks for your response I read the info but can't find the price and were to order?
Did you contact them directly or did you buy them from a dealer?

Thanks again
OEM. so it looks like we are in the same boat. The only other AC regen I have tried is the Furman (cant remember which model). I liked the PS Audio more. Given your low power requirements you could pick up a used PS Audio P-500 for $1200 that would power your entire system.

As for old school R&B...good choices. Of course we cant forget Sam Cooke, Jackie Wilson, Mary Wells...

Please let me know if I can offer any more help.
