The Cambridge S30 is a much better, actually a different class of speaker, than the Energy Take (I own both).
I don't expect brick and mortar stores to provide what I'm looking for in much of anything audio when I'm looking for it any more, but believe the Energy Takes are now discontinued so doubt any store currently selling them. Not sure what stores even sell Cambridge Audio (might check their website, and it's Cambridge Audio, not Cambridge Soundworks). I got both of mine thru Amazon.
As far as avr's I'd look for the features I want, as most of the avr's in the lower price range are differentiated mostly by feature. I'd get the best possible room correction I could and look for pre-outs for all channels; if you're looking for network capabilities of a particular sort or zones, etc. then adjust accordingly. Might look at a refurb (but still warrantied) unit from accessories4less.com as well as the usual culprits.
"I realize that somebody playing free music isn't as commercial as a hamburger stand. But is it because you can eat a hamburger and hold it in your hand and you can't do that with music? Is it too free to control?" - Don Van Vliet (aka Captain Beefheart) discussing commercial success in the music biz
