@Shanling Thanks a lot for all the replies.
I'll ask this to everyone: yesterday I was connected via Bluetooth (ldac) to a Sony speaker. I was at around 2 Mt or maybe a bit more. It played smoothly for around 2 hrs then it started stuttering. I tried replaying other files I played previously without problems ad they stuttered too. After a reboot it stopped but it stuttered again after bit. I'm not sure but it seemed to happen more while using the interface, and less with screen off. As for now still good while wired (but I used it a lot less in this way)
