In the thread "Dedicated Outlet and Amperage - Part Deux" I asked whether installing an isolation transformer in a dedicated circuit would help eliminate noise from other household circuits.
DarqueKnight answered, "Yes."
Now, as I begin planning to install a dedicated circuit to supply power to a pair of monoblocks, I would like opinions about whether that is a reasonable idea: Would the benefits likely justify the costs?
And, if using an isolation transformer for this purpose seems reasonable, how does one determine the right specs for the transformer? At 115V, 15 amps, input each monoblock's rated power output is 750 watts into 8 ohms and 1300 watts at 4 ohms, and the maximum current output is rated at 160 amps.
My thinking so far is that I will install a dedicated 20 amps, 10 AWG Romex line from a subpanel to a receptacle for the monoblock power cords that is a close as possible to the monoblocks (to minimize the length of the power cords). I plan to use high quality outlets. I would install the outlets in an aluminum box holding the isolation transformer (like a Dreadnought box), if I use a transformer in the circuit.
Any thoughts would be greatly appreciated.
