sony zx-507

Dear Headfiers, Want to purchase the Sony zx507 dap and to use it with 64 Audio U12t. I'll mostly use Amazon Music HD along with stored flac files. How does it sound ? Does it matches good with U12t. I would really appreciate if you share your experiences.

Hi all, I'm torn between the two and could use some recommendations. I should note I am not quite an audiophile in terms of optimization and chasing highest fidelity, but I do appreciate the experience of listening to music on a DAP or something other than my phone and enjoy portable devices...
