Your two poll questions are kinda redundant... now maybe if you added more than 1 choice for each brand like Scala G4 or even the Q2Pro (especially for price watchers).
Anywhooo, this has been hashed out quite a bit on my other sites so why not here I guess? I run the SRC (made by Scala) installed within the C3-Pro, can B/B pair with any Scala rider system quite easily. I upgraded to Bose ultra driver/speakers. Beyond awesome sound, my price is also way up there
I have friends with both systems you mentioned. Both have pluses and minuses, let the rant roll on....
