Full Range under $5k-ish

I think Audiotroy's questions are legitimate, his dealer status notwithstanding.  Loudspeakers really are a matter of taste; one person's neutral is another person's boring.

My best advice to the OP is to demo as many speakers as you can, and bring your amp (and your music) to the showroom.  Take your time.

That all being said, I have Vandersteen 3a Signatures, which are full rangers under $5K.  I adore them, and they work wonderfully in my large room, with my electronics (Ayre), my music (jazz and rock), and most importantly, my ears!

Best of luck in your search; let us know what you end up getting!  

OP, I appreciate the inconvenience of disconnecting your amps, but consider bringing just one amp and biwiring to get virtually the same performance.  A Carver TFM-35 is a powerful amplifier and doubt that the impedance characteristics of your speakers' high frequency drivers present any meaningful stress.  The TFMs have a distinctive sound (after all, TFM means Transfer Function Modified) and so it seems all the more important that you test the speaker/amp interaction.

My two cents.  Wishing you well!
