Ok... so I am revamping my entire setup at the moment. Have a Denon 3803 for my reciever, and now I am moving on the the speakers for my system. I am looking to spend somewhere around $2500 total for 5 speakers and a sub. At the moment it appears I am mostly looking at the Energy Connoisseurs and the KEF Q series. For my fronts I am considering either the C-7s or C-9s, or the Q5 or Q7s. I am looking for some opinions on these two sets if anyone has experience with any of them. On a side note... in general is it better to stick to a sub that's manufactured by the same company that makes your speakers, or is it OK to mix and match makes between subs and speakers? Thanks for any help!
