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?

Just in case anyone tries to sell you expensive cabling, I suggest that you buy the cheapest cabling you can find.
Huh, that's interesting.  I have found that cabling is extremely important and just as significant as the electronics you pick.  You can make or break the system by what cabling you buy.

"Just in case anyone tries to sell you expensive cabling,.... "  I think he's saying for now, don't bother to get the nice cables.. Upgrade the components to closer match the Wilsons.. Then save some more and upgrade everything else down the road.. You can get some cheap cables with good design and live with it for now.. 
I'm not sure tubes would be the best match with those Wilsons.  Perhaps I'm looking at the wrong specs but I think they dip all the way down to 1.9ohms.  I would think a used Ayre SS integrated may be a nice way to stay in your budget and get some nice performance.  Try as many options as you can for sure for making a final purchase.
Thanks again yes this is a journey. Need to narrow this down and maybe post with a couple caparisons.
