IMHO if you are into multi-channel music
Then I would go with with the S1's for all
Surround duty. The C5 would be the best
Match for the Tribute...no doubt about that.
I've read that the ADP design isn't ideal for
Multi-channel music. Something about
"Smearing" the sound??
But, remember, I've never
Heard them,much less seen them (except pics)
The "OOMPF" factor to me is powered subwoofer's.
Remember, Paradigm subs don't always equal
Best bang for the buck.
