I heard them in different rooms with different speakers....but the impression was that the P777 had better bass (deeper,tighter and more powerful), was more detailed, accurate and exciting (it had a Class a quality to the sound).....though saying all that, it is not something to get without hearing first.
They can be got at reasonable prices: http://www.hifigear.co.uk/arcam-p777-seven-channel-power-amplifier-in-black-finish.html
My AVR 600 saw off some very good stereo amps (MF M6i; Coda CSI and Moon I7), and the P777 is another step up again....but again that is my subjective taste. All I'm saying is don't rule it out.
That article I linked to is a little OTT, but I don't see much wrong with his (Peter Moncrieff) description of the Tech involved. There are people who have bought two of them and Tri-amped some Kef Refs I think >) .
David from F.Harvey may shed more light on this.
