Coming in late to this discussion, but it reminded me of where I started a few years back. I would make two purchases:
1. Harbeth 30.2 XD speakers
2. Dynavector XX2 Mk2 cartridge
From there you can eventually upgrade your amplification, phono stage and turntable/tonearm. I would also suggest a call to Gene Rubin, who is a master at this kind of plan!
