Speaker help - short list needed

Vandersteens or Ohms...

I have the new C1 sig (a bit beyond your budget) and the esotar2 tweeter is the sweetest smoothest I ever heard. Even The esotec/esotar tweeter is very smooth that are in the models Excite 12/16/32's - Focus 160 - Contour S1.4 would be in your budget. There is a used pair of contour 1.8 mkII here too. Ideally you should demo them first.

Chad329, I heartily agree that Vandersteen speakers will NOT sound harsh or bright. Altho they're pushing your budget a little, I think you should look for a pair of 3As. There are always pairs for sale here.

PSB Stratus Goldi - easily one of the best bang-for-the-buck values on the used market! ...can be had for $700 to $800ish with one of the "premium" finishes.

You'll need an amp with some oomph to drive the 4 ohm load.

A very good all-a-rounder!
