Thank you for the response, my A5.5 came in yesterday and have been listening to it pretty much non stop when I have the time. I am pleased with how it sounds with the 650C and with the sidewinders so for now, as you said, just time to listen and become familiar with the new setup. I am a tinkerer and that is my main reason for looking at different cables, obviously I am after some benefit as well, but I find part of the fun in looking at all of the different possibilities.
As for the A5.5 integrated, it is a nice upgrade from the 650A. I feel as though the lower end has really opened up and there is a new found clarity to all kinds of music. As far as sound goes it has the Cambridge in every aspect IMHO but, and these are small buts, I like the remote of the 650A better and it feels more solid and the volume control through the A5.5 remote is like trying to make fine adjustments with a sledge hammer.
