Thanks everyone for the response.
Boa2, yes my system has changed considerably. I will be updating that soon.
Nsgarch, the XA amps are smooth sounding but definitely on the warm side of neutral which is a bit different that their SS amps.
jafox, your comments are very interesting. Can you explain what you mean by non-linear? So the peaks in the mids give the AA too warm of a sound? You think the Opus is more neutral?
