We sell all three (and are based in Canada) so my assumption would be that all three work in Canada. However depending on where you are some frequency bands may be more populated and could cause interference.
As a Sennheiser fan, it's sad to see how the DW-DP pales in comparison to the Deity Theos Wireless System. I would be really ashamed if I were on the Sennheiser product development team. Please don't mess up when you decide to refresh your AVX system, we need the receiver to be dual channel, and the transmitter should have SD/MicroSD that records backup audio in 32-bit float automatically, so if audio gets messed up, we can use 32-bit float backup and sync the audio. I'm so disappointed because I expected more from Sennheiser.
Is there any specific reason why you are copy/pasting the same comment under *every* single EW-DP review video which is being released? It feels almost like you are systematicaly scanning for new video reviews to then be the first to place your comment. If you are so dissapointed by the system it makes me wonder why you have still spend so much time and energy in looking up new reviews and post your lines.
Have you seen the price point? And have you heard the audio quality? I think they've hit a homerun with this one. But yes, a 2 channel receiver would be awesome.
