Hi jetter,
I had a few set ups. I was using the HCA 1500II for the Vandys and then I got a pair of Aerial Acoustic 10Ts with the HCA 2205 biamped.
While both amps were revealing the recent purchase of the Krell (used) was eye-opening. I wound up selling the 10T’s but always held on to the Vandys and just love them more and more and they were I believe the 2nd version with upgraded silk dome tweeter. Not the more recent signature model. Have since sold all my paramount gear and trying to sell my AVC1500 and CDC1500 on eBay presently
