My reaction, for what it's worth, is that there is little reason for a manufacturer to offer a 2-channel integrated with bass management. By definition, a 2-channel system lacks a separate subwoofer output. If one were to utilize a subwoofer in a pure 2-channel system, the sub would serve to supplement the output of the main speakers, and would usually have its own internal crossover.
Multi-channel home theater systems, on the other hand, often utilize surround speakers -- and maybe even main front speakers -- that have limited deep frequency response, and use the ".1" LFE / subwoofer for low frequency output. The bass management system would, in this instance, allow the pre/pro to "steer" the bass response to all of the speakers + subwoofer, the main front speakers + subwoofer, or to the subwoofer alone.
If you want to pursue a bass management approach with your Plinius integrated, you might want to consider the "ICBM" bass management module made by Outlaw Audio. It's gotten good reviews, and only costs $249. For more info, go to this link:
