I am planning to use Paradigm reference SA-25 for my side channels (in-walls) and SA-10R for my rear channels (in-ceiling), along with Studio 40, CC-470, and Seismic 10. Are there any experienced users for in-walls and in-ceilings? How do the Paradigms compare? I auditioned them at a local dealer and they are pretty good, but if someone has those in their home theater, any opinion would be greatly appreciated. P.S. I am planning to drive speakers either with Denon 3805 or Pioneer Elite VSX 55-Txi mainly because of the digital SACD and DVD-A inputs. Any suggestions? I heard Rotel and NAD is good w/ Paradigms but I've yet to hear about other manufacturers including digital inputs on their receivers/processors.
