Suggestion for new panel/dedicated line

Thanks Zephyr24069 for detailed response and advice, I really appreciate it.

Few specifics about my project

This is going to be my main panel ( not sub panel), It is copper bus and I sent email to Eaton to check if there are bolt on breakers available for this panel.

About in wall Cardas, two of my runs are very short ( less than 15 feet together I guess from mains) so I can give it a try on those circuits at not so much expense)
For other two longer runs, I will use orange romex 10/2.

EP 2050/2750 will stretch my budget out of range right now but I will see if I, somehow, can manage it.

Thanks for advice on ground ref also, I will ask my electrician to make sure that they are same potential.

Best of luck....write me on email if you have any other questions,...always happy to talk audio!!!

Phase I of upgrade is complete. My electrical panel is now upgraded to 200A CH type from Zinsco 100A.
My stereo's mid range is opened up quite a bit. Instrument separation is improved.

Phase II would be done tomorrow ( 4 dedicated circuits).
Two of circuits would be done with Cardas AC 10/2 , other two would use Romex 10/2.

Phase III would be installing EP 2500 on thursday.

I will update/report as my perception of it.

Thanks

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.
