If you are moving locations nearly every year, then my advice is not to invest too heavily in your system unless you're willing to redo it every time you move. Once your system starts getting into the high resolution arena room acoustics start to dominate. So in any given year you may be living in a great sounding room or a real crappy one. The higher the resolution of your system, the more you'll notice the room either for the better or worse. So if you go out and get the SME, match it with a great cartridge, add the Steelhead and top it off with some really good sounding $10k speaker and set it up so it sounds tremendous, who knows, a year from now it could sound like crap because of the room you've move to. You have a very nice system now. Go slow until you settle down.
BTW, the Sony amp is a very good quality amp that should mate quite well with the Revels. It's definitely not the weak link in your system.
