Greetings.

I have Oppo PM1 (home) and PM3 (trips) which I use with Oppo HA-2SE having plenty of power to drive either. I'm looking for portable DAP which has enough power to drive them. I already have Onkyo DP-X1A which is not powerful enough to drive my cans even on high gain.

My preference:

- enough power to comfortably drive Oppo PM1/3 through unbalanced 3.5mm
- big battery enough to run about 10 hours driving big cans
- at least one microSD/SD slot
- supporting all main file formats including DSD.
- Bluetooth aptX (HD)

Preferable but not critical:
- 2.5mm balanced output
- two microSD/SD slots
- Spotify streaming/download


I did some research and am considering Astell&Kern Kann and Sony NW-WM1A. Will appreciate any and all suggestions.

Thanks.
