Looking for seperates under $5k~

Go for 2 Parasound A21 amps, run them in stereo each but use only 1 channel of each.  For a preamp, go with a passive Goldpoint level control.  Each A21 has about 10-12 watts of class A power before switching to AB.  Use some Canare star quad speaker cable, very inexpensive but out easily outperforms anything store bought.  

Odyssey Khartago and Stratos Amps, Plus versions, mono or stereo, also Belles Ref 350a. Rowland Capri v1 and Pass XP-10 preamps. Have not heard the Odyssey preamps.  I liked recent Nuprime gear but have not heard their amp and pre in your price range. I do not like the A21, but this is simply personal preference, many great choices at your price point.

Check out the Belles Statement line.

Nemisis1218,

Bradf's suggestions on used Prima Luna gear is a great option.
A line stage and amp for UNDER your budget that easily will compete with 10k+ combos. You can recoup investment in the the event you don't care for a tube setup. Unless your tastes are for truly exotic or USA made, a good investment. 

Add speakers,source etc of equal quality used, and you may have a 20k retail setup for considerably less

I would jump on those listings if I were shopping.

@gdnrbob  i second the McCormack amp and pre, and having some Steve personal upgrades done. for this will give you immaculate quality sound, and reliability by one of the very best in the game.  MCCORMACK IS THE WAY !
