Have sold on my first DVD/surround sound package, the Sony DAVS 500 (no egg throwing please) also referred to as 'lo-fi' by my KEF Reference owning brother-in-law. I've bought a set of KEF 5005's to make my first bold steps into Home Cinema. My choice for an amp is a Yamaha 750SE at the bottom-end, through to a Denon 3805. I know that there are a few KEF 5005/Denon 3805 owners out there and it comes recommended. Can anyone recommend the Yamaha or is best to go with at least a Denon 2805?
