Vandersteen Model 2CE's: Should I upgrade?

Having used Vandersteen speakers for years, I will answer your questions like this--- The 2ce Signature is a better sounding speaker than the 2ce and worth the change in my opinion. The 3A Signature is what I'm currently using and it is a giant leap over the 2ce Signature. It presents a bigger soundstage with an uncanny ability for the speakers to vanish. Transparency is much improved.
Adding the 2Wq subs to any of the speakers is an improvement. I use a pair with my 3A Signature's. The subs allow you to roll the lower octaves out of the speakers and in the process, allow for more transparency and dynamics. Read up on the 2Wq threads about filter choices.
Using a pair of 2Wq's with the 2ce Signature will definitely improve dynamics. However, Richard Vandersteen suggested to me to go with the 3A Signatures because of the more open and transparent sound. I later added the subs which just augmented an already fine sound.

I agree with the advice given by Bigtee.

I just helped a friend get into Vandersteen 3A's as his first high end speaker. He has lost a lot of sleep lately, staying up late into the night revisiting his music library.

The Vandersteen line is a speaker for music lovers, probably responsible for more people becoming "audiophiles" due it's value to price ratio.

Only you know if upgrading speakers is a necessity for your happiness. If it is, the advice given is where you should go, especially considering your long term satisfaction with the 2Ce.

What they said. I went from the 2ci to the 3Asig and it was a VERY satisfactory upgrade. And you could add 1 or 2 subs at a later date, and also recoup some of the $ via selling the 2ces.
