As mentioned in my previous post, I think you may be spending money disproportionately. The pre-Signature Vandersteen speakers are quite dated sounding compared with the newer versions. The Signatures and MkII's are much more open, alive in the highs, and transparent by comparison. I think you are going to always be limited by the older speakers to some extent.
That said, the Rogue amps sound nice with Vandersteen speakers. I can't comment on the others because I have no direct listening experience with those combinations.
