If I were you I would look at a Madisound Kit or similar if you are DIY inclined as this will save a heap. Zaph Audio/ scanspeak collaboration with Madisound the ZRT is a good bet. I would look at amplifiers next ME, Pass Labs, Accuphase, ARC, VTL second hand are sometimes a bargain. I would run a decent pro PC sound card with XLR out. I use an entry level ASI5111 that EATS most CD players up to $5000. Your computer and its music library are your source. Just thinking aloud you could run a SERIOUS amp with a passive volume control if it has XLR input and out. That is what I run on my PC only I run XLR to RCA out to a flea powered hotted Rogers Cadet III [8w/rms]into ProAc super Tablette with twin 8in bass bins a side run with a custom class A Amp
Loud enough for computer near field monitoring but not a lounge room but I can use the Tannoys for that. $5000 could build you a Killer system as you only need 3-4 components assuming you have a computer. Hope this helps
