Best speakers for 2000-USED

I'd like some suggestions on speakers. Are there any high quality speakers out there that really excell at producing a very big and very 3 dimensional atmosphere for around $2000 -USED. Good tight bass (hearing detail in an acoustic bass in jazz), timbre and smooth detail are also very important. I listen at moderate levels although I sometimes like to really fill up the room with music as long as it remains smooth and clear and not start to get edgy or harsh. My tastes in music range from rock to jazz to pop to symphonies to blues, with more of a emphasis on guitar pieces; artists like R.E.M., James Taylor, The Beatles, Acoustic Alchemy, B.B. King, Pat Matheny, Mannheim Steamroller, Lynard Skynard, Dave Crusin, Dianna Krall,Micheal Hedges, Mark Knopfler- Dire Straits, Heart, ZZ Top. I'm trying to get that sence of presence and 3 dimensionality I get with good headphones.

P.S. I don't drive and there's no audio places within 20-plus miles so I don't get much of a chance to audition. Also; I haven't been in the market for audio equipment for the last 12 years so I'm not up on what's out there that's new and exciting and what's mid to high quality nowadays
