Where do I go from here?

What I have:
Rotel RB-981 AMP
PrimaLuna Evo 300preamp
VPI Prime Signture turntable
Hana ML low cartridge
Musical Surroundings Phenomena  phono stage (originals model)
B&W CM2 speakers
REL T/7i subwoofer (1)
Heimdall II phono cable
He9mdall II interconnects - phono stage to preamp
Transparent Audio MusicLink Super interconnects (preamp to Amp)
Cardas Neutral Reference speaker cables

So, I understand that my amp and speakers are my weak link- that's pretty clear. But Do I replace my speakers and hope they sound right with the speakers I will buy in 2 years, or vice-versa? Or, should I start with different interconnects between my preamp and amp and ho-e they'll work well with the amp and speakers I buy in the future? It's a conundrum you have lol been through, so, what did you do, what would you do different?
