You want dedicated 20 amp circuit(s) with only one hospital grade receptacle per circuit. Think about having separate circuits for amplification, analog and digital components. You'll save money if you have them do it all at once. If funds and local electrical code will allow, having an isolated ground for each dedicated circuit would be ideal. I don't have any experience with the JPS cabling, and I'm skeptical that it is worth the expense. However, I've had excellent results with 10 gauge Romex. Have the electrician use high quality, high purity name brand Romex. They'll want to use the least expensive cable they can find if you don't specify. Let me know how it turns out. Dedicated circuits do far more than any power conditioner that I've encountered, and your amp will never be starved for current!
