Thanks for info Mel, a couple of questions though:
- are you setting up your NAS as a source in Moode or accessing it through a upnp service such as Twonky or Asset?
- was mode a typo and you meant to put Moode app, either way I haven't come across that app on android perhaps given your mention of ALAC you are using iOS?
I am planning to swap out my Pi 2 for a Pi 3 and try out Moode again because SQ seemed better listening to upsampled Suzanne Vega's Cracking through headphones but my wife can't understand why I visibly flinch when it skips! Is it just me or do others have a physical reaction to things like that? Sorry I digress!
I will also try attaching a USB drive to the Pi/Kali/Piano set up to see if it makes any difference - eliminate the variables one at a time
