Spendor S8e or Vandersteen 3A-Sig or ?

I'm considering an upgrade from my Vandersteen 2Ce-Sigs and would appreciate hearing your opinions. Has anyone had the opportunity to audition (or A/B) the Spendor S8e and the Vandersteen 3A Sig speakers?

We listen to jazz, vocals and acoustic folk. The rest of our system consists of Arcam AVR350, Cambridge 850C, with Acoustic Zen IC's and speaker cables.

Any input is very much appreciated.
