Full Range under $5k-ish


So the time has finally come to upgrade my speakers. I mainly listnm
 to vinyl with the occasional CD or AM/FM radio.

Here is my current setup:
Clearaudio Concept w/Concept MM
Parasound Halo P5
2 x Carver TFM-35x (bi-amp)
Definitive Technology BP-2002TL

I would like to stay under the $5k-ish mark.

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!
As most know, I am a Vandersteen fan. 
And, you might ask, why so many have recommended them?
Because they outperform for their price range, and are very listenable. 
But, that is your choice. All I and the other posters want is to guide you to something that we think would be a good move from your current speakers.

For under $5K, you could get a pair of 3a sigs with a pair of 2w/wq subs and be pretty close to a Quatro.
A more attractive option would be to get the Treo's plus subs, but that is probably a bit more than your budget.
Either way, you would get a full range speaker system.
If you let us know your location, maybe we can direct you to a dealer.

+1 on the goldenear technologies, esp if you have some loyalty to ded tech. Sandy Gross is a founder of both.
