You've got a nice rig there too. . .very solid gear that can last a lifetime. My first "modern era" TT was a Project (one of the earliest models) and it got me back into vinyl. I have also owned a couple of Rotel pieces--love their gear and still have a CD spinner around here somewhere.
As for my system. . .the Pre-amp is Balanced Audio Technology (all analog/vacuum tubes). Amp is also BAT (solid state), Marantz SACD player and the speakers are Vandersteen Model 5. I also stream digital via Apple's Airport Express feeding a PS Audio DAC--a great option for whole house sound, convenience, party mode, etc. But for serious listening, it's either vinyl or SACD. Feel free to PM me if you have any questions at all--happy to share my own experiences in audio!
There are some great companies for audiophile quality vinyl but be warned it's expensive (like $20-$30 per album). I love finding LPs at used record stores for a buck or two, cleaning them up and then giving 'em a spin. For 70s and early 80s classic rock, look for Warner Bros. albums (Doobie Bros, Fleetwood Mac, Little Feat, many others). Their vinyl always sounds best to me. I use a Spin-Clean for old albums--it works great but as with all things "audiophile" it'll seem expensive for what you get. On the other hand, it does a great job cleaning records and that's what you're after.
