2.2 Channel System Processor Suggestions

Currently setting up a 2.2 channel system that I will be using for my home theater (have no plans of adding more speakers). I have a pair of ML ESL9's, a NAD m22 power amp as well as two ML 1100X subs and want to use balance connects for all equipment. 
My question is, do I need to buy a Pre/Pro, like the NAD m17 or Anthem AVM60, or is there a scaled down piece of equipment that would work just as well? Most Pre/Pro's have 11 or 13 channels, which is obviously overkill, but I still need something that can support 4k HDMI, has balanced outputs, and would prefer a good room correction software, like Dirac or ARC.

The Classe Sigma 2200i is a integrated amp with HDMI inputs and a subwoofer crossover.  It has one subwoofer output, so you'd have to use a Y-splitter cable.

Otherwise, you're looking at a full HT pre/pro.  The Bryston SP3 and Krell Foundation are only 7.1 processors (they don't have 13-15 channels).  The Bryston has fully discrete Class A analog output stages, so it's much like a high end preamp.

The closest thing I’ve found, that’s not a pre/pro is the Nad m12. The only problem with that is it doesn’t have balanced outs for the subs

What's driving the requirement that you can only use the balanced connections on your subs?  Do you need to run a long cable?  Have you considered wireless?  I use wireless for two of my subs and it works great.

I don't have to use balanced connections to my subs but I would like to. The Martin Logan 1100X subs have a balanced input so it would be kind of silly to use them with unbalanced cables or with their wireless option. Ultimately I want the best performance I can get out of my equipment

Have you listened with your subs using an RCA or wireless connection?  Unless you have really long runs, I doubt you'd hear a difference.

I have not done a balanced and unbalance comparison with the subs yet however I do know that I will be moving in the next year and that could change the current layout of my system. To prevent buyers remorse I would at the very least like the option of having balanced connections.
