From what I'm finding the the dap says "Balanced standard-jack: 250mW+250mW , Stereo mini-jack: 60mW+60mW" For the headphones - 56 ohms at 1 kHz, 98 dB/mW

Alright so I am new to head-fi as well as high end audio in general. I recently purchased the sony mdr-z7m2 headphones which sound great when connected to my oppo ha-2se dac/amp. However I am really looking at a good dap such as the sony wm1a because I want the portability of a single device...
