Eric,
I know that you listen to classical and orchestral to a great extent. I really don't know how you can do so effectively with the modest power of your receiver.
I have listened to numerous pieces suggested by JohnK and I find that I have to turn my Denon up to -2 which is a nominal of 50W/channel in order to hear quiet passages...and even at this level I would say I am not satisfied. This of course leaves me no headroom to speak of with my meager 90W. Now you probably have more like 150 clean watts out of your Onkyo but this represents less than 5dB of headroom. You really are no better off than me.
You and JohnK are great candidates for the A1400. JohnK however is limited by his M22s...but you're not
.
