Someone just dropped cash into your lap

well my amp and preamp are already at the end of the road, so i would go with grand utopias.

Of course the amount can change things, but to give an answer, I would have my SCD-1 SACD/CD player modded.

MIT Oracle V1.1

To answer the question a little less tongue in cheek, my very first priority would be a set of 5 meter XLR interconnects between preamp and amps. I need to do a lot of research before I can determine which would be best.

Pops, I have the MIT Oracle V2 speaker cables and really enjoy them. The 1.1's would be awesome! (depending on system and tastes, of course)

I'm not sure where this fits, but if I had unlimited money I'd construct a dedicated room. I'm at the point where the biggest limitation in sound reproduction is the acoustic environment.
