I tried 8.1.3 twice in my system and really didn't like it - the main problem being with over-bright treble (with AIR). I've downloaded 9.0.1 but haven't had time to install it yet ... son too excited about Christmas
The differences in sound between firmware releases may be down to very minor (but audible) changes in tonal balance, noise levels or both??? If so it's not surprising that there are varying reactions to new FW releases when there are so many possible combinations of input (AIR, AES, USB etc), loudspeaker etc.
