Thanks Crion and Paul for your replies.
Crion - how will I benefit from getting my 3 digital speakers upgraded? Is there really a big improvement to be heard? Sounds like a lot more expense - maybe it's something to think about further down the road.
Paul - It sounds like you really like your C61R - is it a BIG improvement over the 565. Also what do you mean by "forward sounding DACs"? I would also be interested in how you use the PSP? - do you get a small GUI with it?, is it a big improvement on the standard PS3 remote?
If anyone else has any experience of the 565 to G61R (or just G61) upgrade path I would be VERY interested to hear of your experience.
Thanks again,
Conan.
