Joe,
You didn't mention the vintage or quality of your yamaha receiver, but another option would be to get a tube pre and use the yamaha as just a power amp. You can get an audible illusions 2d (mm only) pre for around 400 or a audible illusions 3 (mm or mc) for between 6 and 12 hundred dollars. They have very nice built in phono stages and the rest of your sources would benefit from the tubed linestage. Just a thought. Dlshifi is right, though. Seperates are a slippery slope. Have fun!
