Hi Jgwilson
Since you have a mod marantz sa11s1 why dont you listen to an esoteric in your system (if you have not done).
I have a marantz sa11s1 and AA Capitol Ref se.
Marantz is really good for rock music too - excellent timming.
AA dosent do rock music as good as marantz - timming not as good as marantz.
I dont listen to rock much. But this timming thing was very well evedent in metallica "nothing else matters" song.
When it comes to musicality, AA far superior marantz.
MAY BE AA is a bit slow sounding than marantz,that makes AA more musical .
I have not listen to an esoteric. May be esoteric fills the gap, with excellent timming and musicality
good luck Wilson
