Speaker Suggestions for ARC VT100


I am looking for suggestions on which speakers I should audition. Currentley I am using an Audio Research VT100 mk II amplifier with an Audible Illusions L1 preamp. I listen 90% to large scale classical (think Stravinsky, Mahler & Shostakovich). My room size is approximately 15 ft X 20FT. Price new should be no more than $6k. Hopefully making them used at about $3K or under. However, the cheaper the better!

Thanks in advance.

I'm now running two systems in my house with ARC VT100s, both with ProAc speakers--Response 2s in my study and 3.8s in my living room. I played around for a while in my living room with big Martin Logans (Prodigy) and with small Martin Logans (Aeons), but they didn't really have the slam I wanted for rock. Mind you, they were astonishing with vocals. I auditioned a bunch of other speakers, but ultimately ended up thinking how good the study system sounded and went out an picked up the 3.8s. There is something magic about ARC & ProAc.
I am using my VT100 MKII with Magneplanar MG 3.5s. The combo is extremely musical. Very punchy, robust with tremendous soundstage. Try the maggies.
Thanks for all the suggestions. I am going to plan a road trip so I can hear all these speakers.

Has anypne heard the ARC with either Coincident or Silverline?
