Sub panel & isolation transformer voltage

"Of course, you are still connected to your neighbors junk"
That's where the Isolation Transformer comes into play.

I haven't installed an IT in my new house yet, but years ago I did have one and the difference of quality was quite noticable; deeper, cleaner bass, easier mids and less harsh highs. Much better image on the TV also, better voltage control it seems.

Sure will, it'll be about a month or so since I'm doing the whole room from scratch, about halfway through now. I'll post some pictures if I figure out how to!
