I've just bought a set of the KEF Egg 2005.2's and am undecided which receiver to opt for. The receivers in question are the Denon 2105, the Denon 2805 and the Yamaha DSP-AX750SE. Is the Denon 2105 man enough to do a decent job with the KEF's, or would I be better off opting for one of the other receivers? How does the Higher spec Denon (2805) compare to the Yamaha and the 2105, bearing in mind the price difference between them. Any response would be greatly appreciated.
