If I had the money I'd get the highest quality equipment and have a room soundproofed especially so that I'd get the best sound quality, with no external interuptions, lol.

If I ever see one cheap enough in the future, I'd buy a DVD-Audio player, or more likely a dual Audio/Video player (which most are anyway), with it's own high quality surround system.
My current system is Dolby Digital 5.1 (), and much better quality than my last one (which had a horrible set of speakers; they hissed like crazy), but I've not had it too long, and won't replace it until probably next christmas, as it is quite good.

I just want to make sure that the next one I get supports DVD-Audio, DTS and SACD.
