beginner seperate system


all the listening I do leads to crazy high prices.  anyone out there that can do great high fi on a couple grand budget?  I have nad 275bee bridged mono with focal aria 948.  I would like to experiment with maybe a tube setup or a really reverby ss if exists.  I have a couple rythmik 15 in subs that can do bass.  have a few headphone systems that really have opened my eyes on sound.  can hifi wonky/tubes be done with subs?  and lowest entry point worth the money?  would be great to find something under 5k that can play well with aria speakers.

primaluna always has a lot of buzz around their amps...but always see them for sale on used market...decisions...think Im gonna make a trip to listenup this weekend or next week and listen to their sales force.  bad thing about going to listenup is seeing the new revel be and kanta 2/3 speakers...might put the tubes on back burner and get new speakers lol.  and throw budget out window in process...
maybe just make some phone calls :)
May I suggest something like the lyngdorf tdai 2170 or Antrhem STR integrated. both of these have very well engineered room correction systems built in, plus enough power to run most speakers out there. Reason I suggest these is for the room correction and that ability to make up for other area in your system and also sub integration.
