With an Aragon 2004 I’d go with the Vandy’s. Pretty much agree with the opinions noted above. I owned the 2C and dragged home the CS2 (worked at a shop that carried both Thiel and Aragon) and I didn’t care for them but at the time I probably didn’t have the best amp for the Thiel’s either. At the shop we used McCormack if one was looking for a SS amp to play on the Thiel’s or larger ARC tube amps. The Aragon amps played well with PSB and some of the ProAcs we/they carried at the time.
Your Aragon is a nice amp but I don’t think it will partner well with the Thiel’s. The Vandy’s on the other hand play well with everyone and your amp will do very well to grip the bottom end and the top end should compliment the smoother Vandersteen’s. I owned the Sound Anchor bases and I would strongly suggest finding a set if the pair of 2C’s you are seeking don’t come with. Always best to listen first, but if you can not, the Vandersteen’s are the safer bet IMO. Good luck.
