Suggestion for new panel/dedicated line

Congratulations on the phase I upgrade! The CH panels are good quality and glad to see you are already hearing a difference....enjoy the next steps!

Thanks Zephyr24069, Do I actually need four EP 2750 for four dedicated circuits ?

I will be using one circuit for DAC/Preamp ( Duplex outlet), other circuit for amp. It will be one circuit dedicated for subwoofer and one of later expansion ( may be monoblocks).

I want to keep it in budget for now and not lose on performance.

If you have four dedicated circuits literally, you should put one EP-2750 ground filter on each. I don't see a real need for 4 circuits though; you could put everything you have on one proper dedicated 20-amp circuit or also minimally on two dedicated 20-amp circuits splitting your front-end components (DAC/Preamp, Transport/Streamer?) on one circuit and your subwoofer and amp on the other. When spliting a system across multiple circuits, you have to make 100% certain that the grounding is perfect and that both circuits see the same aspect of ground (not an electrician so don't know the right technical words to utilize). As an aside, I had a killer 7.1 HT setup with all separates for a few years, HT Processor, 2-ch pre-amp, universal transport, DAC, clock, separate amps for bi-amped fronts, separate center and separate (4) rear channels, subwoofer, high-end HDTV, game consoles, video parametricEQ processor (Lumagen) and LFE bass parametricEQ processor; I did NOT need 3, 4 or more dedicated circuits; I ran off one 20-amp circuit and later two at most. I don't think you need to overcomplicate by going to 4 dedicated circuits FWIW....

Thanks Zephyr24069 for response.
My electrician was giving me about same quote for two/four circuits. I am currently using three, one for DAC/pre amp , other for AMP and last for subwoofer. Fourth is unused right now ( future proofing :-)

I ordered two EP-2750, one for DAC/preamp and other for Amp circuit.
I am also installing EP 2050.

I think you will be VERY happy with the results!
