AMP or Preamp


What to add next to my system, budget $5000 to $7000?  My current system consist of Wilson Sasha speakers, Yamaha RX-A3050 receiver that I run pure direct, Rotel RB-1590 2x350 amp, Hegel DAC and a Bluesound Vault 2i streamer.  I have been looking at a Mcintosh C2600 to replace the Yamaha receiver to give me the option of adding a turn table at a later date or would adding mono blocks give me the most bang for the bucks or other options?

I would sell everything and get all mcintosh system. Mc462 and c2600 would be divine pairing.
Thanks so much for the suggestions keep them coming so I can narrow my research down.   PS I didn't want to start an audio war.

Can’t believe someone sold you those electronics to drive the Wilsons with.
Keep the Wilson’s and Hegel DAC and a Bluesound Vault 2i streamer.

Get a Gryphon Diablo Integrated 300 or 120 whatever you can afford 300 preferably, to make those Wilsons sing like you’ve never heard yet.

I got the Wilson's to replace my old speakers thinking get quality speakers and build around the speakers.  My thinking is 1st replace the Yamaha with a good pre amp then work on the amp.
