Dodgealum,
Thanks for informing about the EP2050, and ep2000.com
What is the cost for such an item, since you mentioned it is less expensive than the more conventional approaches?
Their website makes it look easier to implement, too.
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
