I agree with Narrod from what I have been exposed to but, I still wouldn't think of trading my Aesthetix Calypso or Rhea in for a single piece of ARC ever made. No way, no how. Cheers!
so what is the differ albert from ref 2 and mk1 or mk2 and what mk1 or mk2 did they change tubes,and are you saying if it is the model with russian tubes you cant tube roll,and how do you tell what model to get
Agree with R_f_Sayles. I owned the Calypso/Rhea combination before my current Supratek Grange. There is no ARC that can stand toe to toe with that Aesthetix combo and the Grange smokes anything ARC ever made.
please only give me ark responce,dont care if something else sounds better,,,i need ark info..thanks
