im also looking for another small dap for the house, I already have the r3, but have to share it sometimes. How is the bt strength of the m6? With the r3 in a waterproof bag, it is very sensitive to what pocket can be used to not cut audio. Also got a couple of unihertz atom phones for hiking, instead of the day to day ones. If the firmware update improves it, or allow other players like jetaudio or poweramp\audio books might try the m6.
