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

For one, you shouldn't need your sub. Same basic sound, in roughly the same footprint, just taller. But larger scale.
Can be fantastic in the right room with right gear. A bargain.

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?

Thanks gents, as for preamp processor, temporarily I just bought the Integra DHC 40.2 and it works really well with the McIntosh/Vandersteen, and as for cd/DVD/and SACD player I have the Oppo bdp 95. I use my speaker for both Stereo/multichannel and home theater purposes. Also, I like to ask if the 3A Sig. is worth $2500 more than my 2CE Sig II?

As far as any audio expenditure goes, yes. You'll get a much fuller sound, more impact.

If you have a choice, which would you get, a 6 years old 3A Sig. or a 2 years old 2CE Sig II?
