Tom,
If you have dedicateds run, try to have as many installed as you think you might need down the road. It's cheaper by a long shot to have them all done at once, rather than have the electrician come back because you need 1 or 2 more. If you have the whole-house surge done at the same time, it will only add about 200.00 to the bill. It's money well spent IMHO. I actually use both my previous suggestions to you. I have a high current UO for my mono amps on a dedicated line, and another standard UO for my source components on a line, and the surge issues being dealt with at the service panel.
