Welcome to the forum and congratulations on getting a player that you enjoy. If you do decide to go with a Meizu Music Card, I'm sure you'll be extremely happy with it. There is a review by tadad1 here:
Good Things Come in Small Packages
I have a M6 Miniplayer and it has awesome sound and video. I've heard a lot of great things about the Music Card. Check out House of DAP and JTC Electronics. They've got some really good deals.
