ARC Ref150 or Aesthetix Atlas with Vandersteen 5A

Depends on your taste. Some people like ARC with Vandies. I much prefer the TOTL Aesthetix or Ayre with the Vandies.

Definitely give John Rutan a call. Besides a great guy, he really knows Vandy's and which equip. sounds the best with them. Audioconnection in NJ.

I agree with Keithr about Audio Connection. I've done business with them. John's probably the best Vandersteen person out there; besides Vandersteen himself.

Also, with regards to your amp, have you ever listened to an Ayre/Vandersteen system? I know you like tubes (I do as well), but Ayre is not your typical SS amp.

Good luck with your system. What ever version Vand you end up with, you will definitely be happy.

ARC hands down! They are made for each other....

I heard the Ref 5 with the Ref 150 and the 5A's and the 7's and the sound was nothing short of spectacular. If I was being super critical the bass was a little lean in both instances. I heard the Aesthetix amp twice with different preamps and both times it excelled when paired with their preamp. I would lean towards the Ref 3 with the Ref 150 and if funds permit don't rule out the Ref 250. Good Luck.
