What amp next for Vandersteens?

my dad runs a Aesthetix Atlas on his Quats and it sounds fantastic with AR Ref3 pre.

I have the 2Ci, on their original "T" shaped metal stands. I drive them with other vintage, Harman Kardon 17s pre-amp and 16As amp. I am very pleased. I do classical and jazz. I can even do the Telarc LP of the 1812 with the cannons, and feel them, plus hear the small tinkles of a triangle in another part. I assume what you have is similar to my speakers. The H-K amp is biased further in to class A than many - I don't know if that makes a difference. I run them through the original Monster cable - the big round one the diameter of a garden hose. However, I also have heavy duty jumpers at the banana jacks, so not bi-amped.

>Most owners of Vandersteen speakers have either Ayre, or Audio Research

As do I as it was recommended by Richard himself.

I drove my 2ci speakers with a Classe Ten amp and Audible Illusions Modulus 3 tube preamp.  Using Audioquest cables it was a match made in Heaven and kept me happy for 10
