UPDATE:
I can now undertake a more generous upgrade, which significantly changes the picture.
I could address long speaker wire runs (see above response to dynamiclinearity)
I could upgrade DAC.
I found a shop in Seattle that carries various British speakers including ATC (but not Proac, alas) and offers a return policy-- really great news!
I'm communicating with Duke at Audiokinesis re: his Swarm sub array. as suggested by millercarbon.
