I own a Sony NWZ-A17 Digital Audio Player that I've used for the last three years. They are unable to drive my new Sennheiser/Massdrop 6XX headphones.
I'd appreciate suggestions for a DAP that would be a good match for these headphones. I'm not parting with the new headphones as they're much lighter than my current headphones, a pair of AKG 550K.
Seasons Greetings to all.
