I own 5A's and have been very interested in the Vandy 7 sound as well. I wasn't at CES, but in case you have not seen these, here are a couple of links to the impressions of Robert Harley and Jonathan Valin from TAS. It does appear from the written reports from the various trade magazines that have surfaced so far, that the Vandy 7's are something special and as good as Macdadtexas stated. My dealer was there as well and said that Robert Harley's description of the sound is very accurate as to what he heard as well.
