I bought my NDS pre Tidal but I have very much enjoyed Tidal as an additional music source, discovering some wonderful new music and some wonderful new artists. It was however very frustrating when I was experiencing drop outs and that kind of failure is unacceptable. These days drop outs are rare and I am more interested in optimising the SQ available from Tidal - hence my interest in the progress of the FW update.
Tidal however is a secondary source of music for me, but I use it for more than just 'discovery'. Having said this, for me the primary function of the NDS has been, and will always be, the replay of ripped CDs and hi res downloads. It seems weird that anyone would buy such an expensive streamer to primarily play music from a subscription service. Surely not?
If you pay £19.99 (or foreign currency equivalent) per month for Tidal and you are still suffering drop outs then this is unacceptable. But who do you blame, your ISP, t'internet, Tidal, Naim, your own LAN installation? There is or course no guarantee that the much anticipated FW update will fix the drop out issue. We will have to wait and see.
