Curious, but how are you High/Low passing the Mini Marty?
I assume the AVR is taking care of the low pass, but what are you doing for excursion control below the 18Hz tuning of the MM?
Also, where is your low pass for the MM set in the Denon? I modeled up the MM with both the UM18 and the 18DS115, and considering the sensitivity of the 18DS, one might think that you'd have quite a bit more output, but between 21-55Hz, you actually lose output based on modeling with the same power input.
If your AVR is set to cross the sub at 80 or 100Hz, you will see some gains up top in the 100-120Hz region, and maybe this is what you are missing.
If you aren't implementing a high pass I would definitely recommend it since movies are getting more and more <20Hz content and you risk blowing it up. Sure, a lot are still rolling off at around 20Hz, but all it takes is a Blade Runner or Tron at high volume and bad noises will happen...
I am interested to know what you think of the B&C though!
