Understand that the “p” stands for paradise while “m” stands for marvel. Paradise is the newer platform. I think a lot of people skipped paradise that had marvel because they didn’t think it was worth it but if you have the choice going in, the difference is night and day when it comes to bluetooth.
The other issue is the powers of the receivers. Up (ultra power) vs sp (super power). It would probably be easier to get the receivers changed to the right power than get a newer platform HAs changed because it works better with your IT and handles noise better.
Hope this helps some.
