Glory,
I've had both the RWA 30 and 30.2 and loved them. It was only when I got my latest set of speakers that it suddenly sounded a bit too polite for my tastes. It drove me to a Burson SS integrated which cured the problem. I lost none of the attributes of the RWA and gained greater dynamics, extension and tonality.
As efficient as the Zu is, it should be a great pairing.
