Avalon Ascendant or Vandersteen Quatros?

Guys,

I'm returning back to the states in a few months and will be looking to upgrade my 2 Ce Sig II. I really enjoyed a pair of Eclipse's I heard 10+ years ago, unbelievable soundstage and imaging. I hear the Quatros are fantastic as well. I only listen to classical and Gospel and would love to hear your recommendations. I have owned Thiel 2.3, Martin Logan Aerius, Vandersteen 1C and B&W 604 S3.

Thanks :0)
