After some tweaking now my player is up to go. I wasn't going to do a comprehensive review but after fiddling with it a bit this afternoon i'm thoroughly impressed and convinced that it deserves to have all the improvements it has over the Z1060 mentioned and listed. So I'm gonna do that. And will do some video clip to show off the improvements side by side too. I'll post it when it's done.
For a quick conclusion: it is everything Z should have been. Faster, easier to use, smaller, lighter, more portable. It still carries some drawbacks from the Z but fixed a lot of them too. Highly recommended.
Full sound quality impression & comparison (from my point of view) coming soon.
