+1 re: the Linkwitz Orion's!
While I like my Harbeth 40.2's and Legacy Calibre's - I think the Orion's (or the LX521's) may edge them out, when set up properly with the right room / acoustic treatments. The only other speakers I have an interest in are the ATC SCM100-150 ASLT's - but, are cost prohibitive.
Though... there will always be those that I'd like to demo for a while.
