So this arrived and went into its new home this evening:
And the whole system (minus the rears behind the camera):
Sorry. I didn't really clean up for the shot, so pardon any dust!
I was surprised that it's actually a touch smaller than the A308 Integrated it replaced. Also seems to run a bit hotter now that it's been going for a while and breaking in a bit. I'm not a big suscriber to burn in, particularly on electronics, but I do tend to give things a few hours before judging too critically.
I wasn't expecting too much of a difference between the two, but after settling in for a couple hours, it does seem like there's a touch more fine detail in the upper midrange to highs as little things seem to stand out just a smidge more. I know... Audio memory and all that. Still, it's a welcome find.
