As per my reply to the other htread asking the same thing.......
The Yamaha, as far as surround sound is concerned, produces a far bigger soundstage than any amplifier in it's price range, giving a more believable and enjoyable experience, so you can imagine how it compares to a cheaper amp. Quality-wise, you're comparing what is a £300 amplifier to what was originally a £600 one. With less than £100 between the price of the two at the moment, the decision should be no contest
