Is there a huge diff, between 2CE Sig II & 3A Sig?

Everything improves a little and there is a big improvement in the low end. I feel the best bang for buck with vandersteen is the 3a sig with the 2wq it just taks room. I had the 2ce sigs for years and enjoyed them quite alot they are a great speaker but they needed the 2wq.

It is hard for me to tell you what difference in your system you will hear since you areonly stating your amps and I have not herd thoes ampes on vandersteen anyhow.

The Velodyne sub scares me a little I love velodyne subs but they woud be a bit slow I think paired with vandersteen for music and how are you crossing it over anyhow. Are you using a receiver?

Still hard to say the 2ce I was running quicksilver v4 on with kimber cable and a asethix pre amp and every change I made to the system herd the speakers where very transparent. As I said the 2wq made a big difference. The 3 will be a bit cleaner I think it is the sweet spot in the line.

Anyhow he is alwas improving little things. That does not mean an old set is bad. If it was a huge improvement it would dictate a model name change.
