My suggestion to you is to go to eBay and/or surplus outlets and look for something *industrial* rated...
I have a ONEAC isolation transformer (220V in/ 110V out) in a small apartment. I unplug the stove when I want to use it. The difference in slam is more than slightly noticeable. I figure that by getting straight 220 I get way more juice. My power amp sounds better when plugged to the ONEAC.
I'm pretty sure you can find something industrial rated that you can use for your entire house.
