Vandersteen Model 2CE's: Should I upgrade?

I'd like to thank all of you for your insightful comments. Since it looks like I will be looking very seriously at the 3A Signatures, do you think that I would be able to power them with my Bel Canto EVO 200.2 or will I need something more powerful?

you can also get 2wq to add to your existing 2ce. you can even get a pair of subs that will bring your system far better than with 3A's. you will have benefits of bi-amplified active system that you can adjust to perfection.
overal vandersteens havn't had any major improvements over the past 10 years and sound basically the same.

Unless you have a very large listening room, or tend to listen at "ear bleed" levels, you Bel Canto amp should be a very nice pairing with the 3A Sig's. Since you've raised the question about power levels for the 3A Sig's, you should be made aware that Vandy speakers are less well suited to playing at very high SPL's, compared to some other speakers. The Vandy 3A / 3A Sigs are of medium efficiency (87-88 db) , and they employe a 6-db, first order crossover, which somewhat limits their ability to play very loudly. If pushed to high volume levels, Vandy speakers may compress the dynamics a bit. I have driven my various Vandy speakers quite effectively using a low distortion 125 wpc solid state amp (although my current amp has about 300 wpc). Based on what I have read of the Bel Canto Evo amps, they have good dynamic headroom, and good bass control, so yours should be fine with the Vandies.

you'll love either signature series.

I agree that your current amp should be fine. The Vandersteen's as a whole do require power. I'm currently using a Belles 350A (250/ch @ 8 ohms) I have never felt the amp was remotely stressed for loud levels. I did use McCormack .5's back a while (rated at 100/ch) Thought they did fine but honestly didn't sound as refined and powerful as the Belles.
As a passing note, I can't agree at all with the sameness statement of the above gentleman. I have found an improvement as you go up the line although it is a less of one between the 3A and 2Ce Signature. The 3A Signature IS a jump above these two. The 3A Signature uses the Model 5 tweeter and midrange. This is a quantified improvement in drivers over the 3A and below and it shows in its performance. Also, when speakers and/or drivers are utilized correctly from the beginning, there is no need to bring out a new improvement every year. Vandersteen upgrades when genuine improvements come along.
