New Subpanel?

I used to work for electrical company. So I know all the basic of installing the subpanel. The subpanel will be 120/240 with 60 amp feeds and 4 dedicated circuit to the room with #10 wire with hubbel hospital grade plug. I am still debating Romex vs conduit. Is there any benefit to use conduit? Even thought I calculated all the load to be around 2300 watts which is a 20 amp circuit would do. As for the panel I would take your recommendation of the Square D Panel I prefer the bolt breaker which cost a little more :)

My audio systems list:

1. Mcintosh MC2000 Amp (2)
2. Mcintosh C2200 Preamp
3. Mcintosh MCD1000 Transport
4. Mcintosh MDA1000 DAC
5. B&W 802D Speakers

In the future I would add a plasma or LCD TV and make it into home theater for my other half.


Thanks again

I asked you questions about distances. Why do you need, want, a sub panel? Is your equipment a long distance from your main service panel? You mentioned the sub would be 120/240V, are you planning to feed the 120V audio branch circuits from each line to neutral. Best to feed audio equipment connected together by ics from the same line. L1 or L2, not from both. If you agree, why not wire the sub 120V only? If you would, finish answering the rest of my questions.

The distance from main panel is around 75 feet but when you wire around all the obstacle is around 110 feet. There is not enough room for more circuit breakers in the main. I didn't know that is best to use the same LINE (L1)or for all audio equipments.

Thanks

Now I know why you want and need a sub panel. If you have the money you may want to consider another option, an isolation transformer with an electrostatic shield like that of a Topaz. Feed the transformer with 240V, transformer output 120V. The output would then feed a small panel by a main breaker. Do you have a space near your equipment for such?

Is interesting so you suggesting an isolation transformer. So the output power would be pure so I don't need to worry about power condition which in turn save me some money on the power condition or power cords which it will pay for the isolation transfer. What is the type of isolation transformer you suggesting. I do have room for the transformer.

thanks
