ARC hands down! They are made for each other....
ARC Ref150 or Aesthetix Atlas with Vandersteen 5A
I will be getting a pair of Vandersteen 5A's or 5A Carbons in the coming year. I will be replacing my amplifier first in the very near future. I have an Audio Research Ref 3 preamp. I have a good size collection of classical, jazz and rock on both cd and vinyl. I'm tossed between the two. Any thoughts as to which might pair better?
