I have recently purchased Frank Sinatra Album, Ultimate Sinatra: The Centennial Collection - from HDtracks.
I have notice that one of the tracks (44) it simply doesn’t play over the ethernet (streaming), it get stuck in the end of nr. 33 and after some minutes skips to number 45.
this issue doesn’t appear while playing over USB port.
Not saying its an AIFF problem, but it has a familiar ring about it.
A few years agp I was given some albums in AIFF (sourced from iTunes I believe) & my NDX had a issues such as refusing to play tracks. I was using WAV at the time & a dBpoweramp convertion to WAV fixed it.
Why not convert the whole album ??
Also consider converting to FLAC, whilst it was true WAV did sound slightly better on older (legacy) Naim streamers, its not the case with the new generation streamers.
