looking for upgrade suggestions - 12,000 to spend


I am looking to upgrade my current system. I have $12,000 to spend BUT don't know what the most substatial/practical upgrade would be for the $$$.

Rowland model 10 amp
Rowland synergy I pre-amp
Levinson #39 cd player
Dunlavy SC-IV speakers
synergistic des. ref and FIM cables/power cords
2 ASC 16" tube traps - in the corners behind speakers
room size 12.5 ft wide X 18 feet long X 8.5 ft tall

I was thinking new speakers (Avalon, eggleston, kharma,talon,dunlavy)OR using the #39 as a trasnport and getting a DAC??

Can anybody make some suggestions OR point me in the right direction??
Thanks - Chris

I would place a bet on Avalons They're a bit hard to drive but not with Jeff Rowland (a true full range speaker is always hard to drive for what I believe)
