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.
Amplification:
Citation 7.1 amp (4 x 150)-will bi-amp or bridge to
2 x 450-Which is best?
Adcom GTP-750 Pre-amp-another Citation 7.1 in the sys.
for movies
CD player:
Luxman DZ-111 (old 16-bit dual DAC unit
Cambrige Audio D500-SE
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

Great advice from Reubent, but I would try and stay with some more sought after companies also if resale is to be an option if you don't care for them. I would have to add B&W to the list for your styles of music. They play everything from heavy metal to jazz to synphony with great results. Remember to keep your objective clear and always have fun buying and trying. Happy listening!
I'd consider the Triangle Lyrr ($3700 new, about $2000 used). See review at http://www.soundstage.com/revequip/triangle_lyrr_xs.htm
I second the Magnepan recommendation, but if they are too big and bulky a used pair of Thiels has phenomenal imaging as well.
The 7.1 is a nice amp. I'd go with a pair of Apogee Duetta Signatures full range ribbons (~$1400). Then get a Marchand electronic x-over (~$300...if you can find one)with a 400 HZ module. The Duettas then can be actively bi-amped. The 7.1 makes it a snap! This setup will be fantastic for the type of music you like.
