Sub panel & isolation transformer voltage


Is there an advantage hooking up 240V to the IT then stepping it down to 120V to the sub-panel or is 120V straight good enough.

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.
Homer, please post when you install your new IT, what model you end up getting, and the sonic results. Thanks!
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!
