I hoping some members can possibly give any impressions of those models or recommendations. I can say at least with the OMD-5 I currently have, I don't have any perceived blending issues with my front 5. So I am going to assume I won't have any blending issues with the OMDR. I read some of the owner reviews though professional reviews of the OMDR are hard to find. Demoing those two would be ideal and would solve the issue but that is going to be near to impossible. Thanks in advance for any help.
