Question for ARC aficionados

Read the ARC VSi60 review in this months (Sept) Stereophile by Robert Reina.
He gushes all over the VSi60 saying stuff like "....cut from the same cloth as the Ref 110", and more. He can`t stop drooling over it!

You would be giving up a heckuva combo.For what?One box?Tough call,YMMV,Bob

You will be gaining!
I had a ls26 with a pair of Manley Snappers,and also tried a VT100mkiii
I like my VSI60 much better.
Great bass,incredible soundstage,etc.

Efner, your response is quite intriquing. I am considering downsizing because the VT100 mkii is quite expensive to re-tube and somewhat difficult to adjust balance and bias. It is also quite heavy and puts our lots of heat. I'm looking for something smaller, lighter, and easier to live with. When I saw the Stereophile review on the VSi60, it got me to thinking. My only question then was, "would I be giving up anything sonically ?" Maybe the answer is "no".
Has anybody else out there made the switch "down" in the ARC line? thanks for all your answers.

The spec's on the vsi55 and vsi60 seem identical. Did that much change in the two amps or is this the usual (and probably justified) need to make a few changes and increase to cover the costs of business. For instance the optional tube cage was $200, now $500. Maybe it's not the ugly perforated on anymore...

I ask because I heard the vs55 next to the newer 60 and couldn't make out any differences. Even as ARC web literature goes they typically go on and on about how the new version kills the prior, but no mention of this either.

Not knocking ARC, love the company, just looking for answers.
