Aerial Acoustic's CC3B

Hi all,
How effective is the "environment switch" of the CC3B? I'd like to demo a CC3B but would like first hand experiences from owners first.

My mains are Dali Euphonia MS4s and I recently bought the matching center, CS4. I don't listen to 5ch audio so center is strictly for HT. The CS4 is on top of my RPTV. It's huge and I have some concerns about the weight, and room behind the speaker. I was wondering if it might be more practical, save some $$ and go with the CC3B, which doesn't necessarily mean a downgrade, sonically.

Thanks in advance.
Happy Thanksgiving!!!!
