Re: Matching Paradigms - Sound Continuity
I would go with the higher end front end (Studio 20s across the front) and atoms for the rear. The sound quality of the rears are not as important as the front as most of the listening pleasure is at the front. On that note it is very important to have the left, right and center to be sonically the same.
I personally do not not have a center channel as I still have not found a setup where I am happy with the front sound field. Ideal is to have three identical speakers up front, at the same elevation, equal distance from the listening position.
