Need some advice please.......

I currently use an Apple TV into a Remedy Reclocker into a PS Audio Digital Link III w/ level 3 Cullen mods to send my PCM files to my music room wirelessly.
Cables are good - Belkin Synergy Platinum Professional. I'm very happy with those.
I expect to have a few dollars (maybe about $3K) fairly soon to spend and I think I want to improve my wireless setup. How would you guys suggest I improve things based on the above?
