I'm curious- why spend all that money on a DAP capable of bit perfect playback with dual DACs and use Bluetooth? You're losing all of the benefit of the DAP.
My iPhone’s battery was dead, so I thought let’s try the R5 for my walk. All my files on the R5 are hi res, but I do have the Radio Paradise app which plays 16/44.1 flac, so I’ll try that and see if it works better. I should add I speed walk, so the R5 was bouncing around in my loose fitting shorts.
Normally, my R5 is used exclusively at home since it is the only android based dap I own, the reason I bought it. If it turns out the BT isn’t up to snuff for my walks it’s actually not a big deal for me, it was just a moment of frustration. Sorry for being alarmist.
