3 player shortlist, help me make a choice.....

The previous suggestions are all good. I have one concern about your existing system. The LS2 (I owned an LS2B for three years) is very bright and a better digital front end might not sound good to you through that line preamp. I replaced mine with a Sonic Frontiers Line 3 and the improvement was incredible. I liked the LS2B in a lot of ways but it could drill you into the wall with bright treble. If your system is not bright now then disregard my comments. (I was driving a Krell KSA200s and Thiel 3.6s..all on the bright side.)
