Advice- wiring for dedicated sound room

I'm building a house at present and am almost ready to start discussions with our electrician. I'll have a 19'x24' with 9' ceiling dedicated soundroom/theater. (No windows!)

I'm asking for advice on wiring it up just right from the box to the walls. Obviously, I know I'll need some dedicated lines and I do intend to use hospital grade 20 amp outlets. The house is to have a 440 supply. Should I suggest a 10 ga Romex vs. any other options?
What about grounding?
Any comment on breaker types for best performance, or the addition of fuses outside the box?

In the soundroom itself, if I use the hospital grade outlets, should I still use my conditioner, sequencer (Adcom 515)and connect my equiptment that way. Would I lose the advantage of the outlets and current flow if I don't hook directly to them?.

Thanks for any ideas.

Thanks for the input. I appreciate your advice and I can incorporate some of ideas easily enough into my building project. I'll be better able to explain to my electrician what I want and why.

Thanks again.

Abstract7, Could I assume that the secondary winding on the toroid is center tapped and you grounded the center? That would give you the out of phase balanced =&= 55 volts. Some isolation transformers may have a center tap but I am not sure that it is absolutely necessary to ground either leg of the 110 as long as the safety ground is intact. Can anyone in the know comment on this. The main reason for the isolation transformer is that many have a faraday shield between the input and output windings that helps to prevent noise from getting thru. Electrical supply houses can get multi-KVA transformers that can handle 50+ amps.

Audioken, If your new house is actually going to be 440 volt (and you are in the USA) you will need one of those big step-down transformers feeding the distribution box. Let me know how hard it was to get the power company to install 440 service. I will do it for my garage so I can force them to put in a single transformer on the pole just for me!

Sqjudge: Yes the ground is center tapped. I had to go back to the wiring diagram to figure that one out, but that is how it's done.
