So you want to rebuild the whole thing regardless of money !?

Hi.

May I ask what system you are now using ?

Hello Jack,

We are willing to commit a lot of money to the project if it will make legitimate improvements. There isn't a blank check on the project, but I am sure we are willing to spend more than most. Let's throw out a figure of $8-10K. As I said, we don't want to do this job more than once.

In the time since I wrote the original post, we have been looking at a total of 10 lines. We are thinking of making 5 of them 30A JPS wire, and the other 5 30A Romex. This will reduce the cost of the project significantly, and at the same time still provide premium wiring for the core 5 outlets in heaviest use.

We are thinking 2x30A circuits for monos, 1x20A for digital sources, 1x20A for phono stage/preamp, one 20/30A for TT power. We might make one of these 30A just to experiment with using it for the Television. Depends on how much more a 30A "industrial" breaker costs than a 20.

What are we using? Usually I don't like to say in the interest of privacy/security. I don't like just anyone with a net connection to know what's in my living room. I will send you an email.

All the best,

ccm

  The JC-1 draws 1280 watts at full power into 4 Ω. I would think one 30A circuit for both would be plenty. I am no electrician, but you may want to investigate a whole seperate panel right within, or close to, your listening room. The seperate panel could be run directly from the meter box. This would shorten the runs & lower the cost of the JPS wire. I think 250A of service is waaaaaaay overkill for a home audio system. I would concentrate on the five 30A circuits and pay more attention and money toward the outlets / circuit breakers / power cords. There are audio(phile) companies that will cryo treat wire, breakers, etc. for a small fee.
  Two more things:
  You need a minimum 10GA wire for 30A circuits.
  When you add all this additional capacity, you need to have the electrician check the rating of the meter, and replace with a higher capacity meter if necessary.

    Thanks for your post maabx,

    Well, eventually, we hope to experiment with a system with five of them, plus two dedicated high current stereo sub amps. I think Racerguy's suggestion of 60A is probably appropriate, but if we end up adding 100A of service from 100A to 200A, the extra 100 will probably just go to the second panel and then we never have to think about it.

    Yes, this looks like the way we will go.
    
    > The seperate panel could be run directly from the meter box.
    
    Excellent.

    Agreed. That was back when I was thinking that the service value had to be more than the sum of the breaker values.

    Any examples?

    Yes, thanks, I knew that.

    Thanks - this will be part of the discussion we will have Fri with our electrician.
