Yes, but having both in my home at the same time, unless I'm just missing something, XT32 is easier to tune and with more tuning-ability than with ARCG. However, like I said in another thread, on the whole, I like the sound of the Anthem in my setup more than the Denon X3700H. I MIGHT be able to fix what I don't like with the Denon with even more time spent, but I've spent probably 3X the time running Audyssey and playing with the App, A/B testing against the 2 presets with minor changes of the same graph between the two during the same song, and yet I still haven't gotten the overall sound, on the whole, to be as good as the Anthem. Speaking strictly to bass management though, it's been easier and better with the Denon.
That said, because I have multiple subs and a difficult room (I have been running 3 mostly, but have a 4th in place that I've been playing with), I'm going to go pick up a 3800 today (same as the C50 right?) to see if the 4 sub inputs does anything for my room. If it doesn't do anything any better than the 3700 for me, I may just keep the Anthem and pick up a miniDSP.
Have you tried limiting the RC range to below 500 Hz? Depending on the speakers and room, XT32 may not do well in the range above 300 Hz.
AARCG limits it to 5000 Hz by default but XT32 defaults to 20,000 Hz.
Given that you have either XT32 or AARC, the minidsp is likely a waste of time, based on my experience, ymmv though.
I can sell you mine for $100 but I wouldn't recommend it.
