Best amp for Vandersteen Quattro?


Hope someone can help - I have a Mark Levinson 380s pre with an old pair of Electrocompaniet AW180 monoblocks currently powering my Vandersteen 2 sigs. I have bought Quattros and I am expanding my system for HT use and would thus need amplification for three more channels - I plan to move the EC's to rear channels and need to buy an amp for the main speakers - what do I buy to power the quattros? As I understand it (with the built in subwoofers of the Quattros) I do not need ultimate bass grunt but need an amp with a sweet and open mid and treble - am I correct? My budget is $5000.
Thanks

The only caution about the McCormack amps is that the input impedance on some models is too low to be compatible with the required M5HP (high pass filters) used on the Quatros.

They are nice sounding amps though.
I have heard them with Ayre, AudioResearch and Classe amps all with outstanding results (my dad owns the wood Quatro)
Give Richard a call and find out what he recommends. I'm sure he has something to say. More than likely he voiced them using a particular amp. (559) 582-0324
Sanders ESL monos produced some of the most realistic "life" sized images with great treble purity.
Theta Dreadnaught. I have used it with Vandersteen 2CE Sigs, 3A Sigs and Quattro speakers with great results. Smooth, extended and warm without any slop or overhang. Good luck!
