Best speaker 3k to 4k used?


What do you think is the best speaker in the 3k to 4k range(used)? I am using solid state electronics(Gryphon S100 & Tabu preamp). Room size is 14' x 20'.

Dynaudio Contour 3.3 or Silverline La Folia. Dynaudio probably has better integration, but Silverline will go deeper and probably has better midrange.
Third recommendation for Aerials - for your amp and listening tastes the model 6's would be perfect (yes, I use them too..). I use a 100 w/ch Rowland integrated - the combination is fantastic. I use them even in a decent sized room (21 X 13) and only need to turn on my REL Storm for heavy classical/organ music. Try to find a similar 3-way speaker (the key word, 3-way), with trickle down technology (same tweeter as 10t) and this level of build quality, for the price of the model 6. I have yet to hear a speaker under 5k that sounds better overall... It certainly is one of the best values (used) in high end...
A pair of Gershman Acoustics Avant Garde RX-20 (demoed or used). Read rave reviews in the press.
