I bought my Magnepan IIIa back in the day because I heard them on VTL300's. I think the extra power that the VTL provides over the ARC is the biggest benifit for you. Plus VTL's are easy on tubes compared to the ARC. Individually biased tubes on the VTL's versus expensive matched quads, sixtetts, octetes that the ARC stuff typically demands.
I almost bought the VTL450's for my Wilsons after hearing a pair power WP7's. I listened to the VTL S400 with the smart tube technology and it was magical but unfortunately not enough current to drive my Wilson Maxx's at the levels I like.
