I'm seriously considering one of these as a centre speaker as I'm finding it difficult to place my big Ruark Dialogue without it looky silly. Firstly, anyone got an opinion on how it will compare to my Ruark in terms of sound quality? I have a Ruark sub with speakers set to small. Secondly, I see they are rated at 30w at 8ohms. I have a Denon 3803 at the mo. Will that destroy the Linn? WOuld I need a smaller power amp for that channel and if so, would it be too quiet. Lastly, my walls are 2 foot thick stone (proper stone, not brick). I'm pretty handy so is it possible to make up a box or something for the Linn? Advice appreciated.
