You can call me interested, I'd love to see a successor for X7mkii that has the same amazing sound of X7mkii, but the software of M9
The more I think of it, the more it makes sense to drop the X series in favour of more modern architecture and expand the M series upwards.
I'm a big Fan of the X7 MKII, Fiio has done a very good DAP, one of the best.......but.... they also have done the worst app/UI ever to use. No, seriously, I've tested many, many, many music apps and this is the worst ever, period. Fiio, if you read this or any other forum, please take note of the disappointment of your user/fan, and take action to correct this ASAP. Take exemple of “PlayerPro” music app, one of the best, fluid, ergonomic, so many features and bugless. I'm going to rollback to the previous version.

I want that! And this time not for music, but really for 4K video recording, it would have just the right speed! With dual microSD cards, 2X 512GB seems to be doing the trick with X7mkii for me, I just don't have 2TB of music yet, even if we count my hi-res collection
