First post for a long time driven by my recent upgrade from NDX to ND555. While the sound quality is clearly better, it seems to me the control functionality is worse, although I might be doing it all wrong! Apologies if any of the following has been addressed already, but I couldn’t find anything on a quick search. Firstly I can’t believe you can’t select the Unitiserve/uPNP server directly from the remote/head unit but can do it only via the Naim App. This seems a real backward step and very inconvenient for me. Also, you can select Spotify directly but not Tidal! This also seems unbelievable: who with an ND555 uses Spotify? Further it seems to keep shutting down the Unitiserve when used, though perhaps that’s my set up, but then won’t recognise it even on the Naim App ‘servers’ button, so can use only Tidal. Lastly whenever I change the ND555 input (between say Internet Radio/Tidal/Unitiserve) it forces the 552 input selector to CD (it’s connected to AV; I still have the CD555 on the CD input and don’t want to change). It is frustrating to have these issues with an expensive product, which seems worse than the older, cheaper model in this respect, although of course the SQ is as much better as it should be… Are there any ways round these inconveniences (the manual is sketchy at best) or might future firmware updates address them?
