I think that would be a nice option at least for stereo music processing.
It is definitely possible for Auro-2D to have audio emanating from the back surrounds. In fact, this is the first instance we have come across where it does not (although we haven't fully comprehensively evaluated all products that make use it) wherein IMO it's kinda the best and most useful feature of Auro-2D, being able to upscale all of stereo and 5.1 audio, particularly music, to 7.1
The legacy upmixers Dolby Pro Logic II, IIx and IIz are superior to Auro-2D, which I have been repeatedly pursuing with Steinway and Lyngdorf to be added to both the MP-50 and P200 processors; but because of the complications involved with respect to doing so, I asked them to add Auro-2D as the next best thing; which is why I love these guys because they always listen to and look after the best interests of the customerbase.
I had yet another conversation with them whilst at CEDIA last month and followed up with respect to them adding the legacy upmixers Dolby Pro Logic II, IIx and IIz. Suffice to say, if they can they will, but there are no guarantees that they will do so, because it's not as simple to achieve as some folks think it is. That said, it would certainly add an extra USP to the MP-50 and P200 if they do add these, in addition to the Auro-2D, wherein many audiophiles, myself included, would greatly value the addition; and I have told them so.
Either way, there's a need for an upmixer to upmix stereo and 5.1 audio to 7.1. Auro-2D is definitely capable of doing so, but currently seems to be malfunctioning. So hopefully Lyngdorf can and will fix this. What I can say is that having heard it many times previously operating properly with audio emanating from the back surrounds, as intended, it sounds great.

Personal preference is going to be key here because there really isn't any 'one shoe fits all' when it comes to the various post-processing options / upmixers. A lot is going to depend upon your particular speaker configuration, which type of audio you are playing (e.g. stereo studio music recording, or 5.1 surround music live concert, or 5.1 movie etc...) and your own particular personal preferences. For the same reason there is no 'right' or 'wrong'. So my recommendation is simply to try them all out with respect to whichever type of audio you are playing so as to get a feel regarding what they do and how they sound and simply use whichever you like best. Some folks prefer the Auromatic upscaler for music, others prefer the Dolby Surround Upmixer, whereas others will only ever listen to stereo music played back as stereo citing that's how it was recorded so that's how it was/is intended to be listened to. Everyone is right and nobody is wrong. What's most important is what YOU prefer. So my advice is to simply have a play around and see which you like best.
