I will suggest you buy a used PS Audio PP-600, plug it in one of the outlet of the dedicated 20-amp line, and plug all your front-end audio equipment to the pp-600. I will than plug the power amp to the other outlet of the dedicated 20-amp line. This will give you a regulated power and isolation for the sensitive front-end and a star grounding connection of all your equipment. Star grounding is the key to eliminate ground-loop problem.
The PP-600 will cost you a few hundreds more but the cost/benefit ratio is much higher than UO+Monster. You don't even need the latest PP-600. A used one without powerport should run about $1500 on Audiogon.
