What’s your opinion about Dali speakers?

As others have stated, not nearly enough information to respond effectively.

Do you have a Dali dealer near you?  Have you heard Dali speakers before -- especially in a surround configuration similar to what you're wanting?

As far as their sub woofers go, skip them until the new ones come out.  The current ones are not competitive at all.  They have new ones coming that will be outstanding.

We would gush about Dali speakers as they have gotten response unlike any other line we have ever dealt with, but that would be tacky.

It's critical to be aware of the fact that anyone with an impression of older Dali speakers does not apply to anything new.  As with any brand. 

The new Dali Rubikore speakers are actually better than the 10 year old outgoing Epicon (less than half the price in most instances).  Aside from the cabinet design of course.  Although the new Rubikore finishes are gorgeous, it is still a "box."

We encourage anyone whos latest Dali experience is with 10+ year old speakers to listen to current models when comparing to other current models.  ;)
