Anyone compare the ZTPre to the Anthem AVM 90 sonically?  Yes, I know they are completely different beasts, but I' curious about the musicality of the AMV 90.  I have a ZTPre and love it.  I also have a Marantz AV8200A, which I do not use for listening to my music (mostly digital > 96k, sources from an awesome DAC). I'm 70 years old, so my hearing is not what it used to be.  Looking for opinions.
