Music channel change?

I have been thinking about getting the Grace Digital Mondo Elite radio and a streaming only subscription. Do Any members know if it gets all of the higher numbered channels?
I have a Grace Digital Encore and it goes up to Channel 508 and then into the Xtra channels.
I see a lot of people saying that they don't like the new app. Trust me, I don't adjust to change very well. But the new app works for me. NOW LEAVE IT THE F ALONE.
