I’m quite happy with my Onkyo TX-NR3007. Took a little to adjust to the Onkyo way of doing things from the Denon way but in the end the functionality is the same just how you get there. As Tom says if your plan is simply to use this as a preamp then the 1007 should do the job I’d just compare the features to make sure you’re getting what you need.
As far as the Emo I’d stay very far away from any pre-amp they offer. From what I’ve read all of the UMC-1’s problems can not be fixed via firmware. The bass management in inherently flawed and it does not do true HDMI pass-through if you want that feature. These two things and possible others will not change.
