Suggestions for medium priced Power amp and Pre-Amp Combo's

I have a pair of very good Magna plane type speakers and would like to build a system to power them.  I have always wamted an amp/pre-amp set-up, probably tube, but that is where I want your help.  I love Jazz and want to hear the instruments.  I want clean sound.  But I would like to keep the combo under $2K if possible, but more importantly, reach that quality level that maximizes sound quality without getting ridiculous on price.  Like buying a low end BMW, still getting the performance, but not at huge cost.  My listening space is very bright acoustically.  Thank you!
