You could probably find a used pair of the Vandy 3A's (not the Signature model) that is within your budget. Last year, I bought my son a "low mileage" used pair of 3A's AND a VCC-1 center channel for $1500 for everything. If you post a "want to buy" here on A-gon, you may find a similar deal if you are patient. If you get the 3A's, you can have them upgraded to the Signature model sometime in the future. Both the 3A and the 3A Sigs are a significant improvement over the 2Ce Sig's.
Vandersteen Upgrade Path
I currently have the Vandy 2ci, the 2wq and the Vandersteen center channel for HT (not sure I really need it though since I usually sit right in the middle). Anyway I am thinking of upgrading and was wondering if it would make sense to add a second sub or get the 2ce signatures and continute to make to do with one sub (at least for now)Upgrading to the 3A sigs would be too big a stretch on my budget (unless I sold off the 2wq and center channel that is). Any thoughts?
