IS VAC really better than ARC?
Both are top notch whenever I hear them. Not sure how one can be said to be better than the other.
ARC has been around longer, is much bigger, and a better known quantity for sure I would think.
VAC is still more of a boutique type brand I think. Still a very reputable one as well though, as best I can tell.
Definite practical differences that might matter to most though.
I have heard way more ARC demos than VAC. Have never heard a clearly bad one with either, usually just a matter of overall system synergy case by case (as usual) and personal preference which might go either way.
At least that is my assessment based on what I know and have heard to-date.
I could live happily with either, and would probably look no further than these two for the cream of the crop as well, though I have many others sound really good when set up right as well.
