I would like to see a music server without a streamer. 2TB or 4TB pre-fitted SSD or your own. I think people who use a NAS today will be very interested and it shouldn't be too expensive. In general, I think your products have become very expensive.
Well, it sounds like you already have a low-noise server run by Sense!
Keep in mind the things that make a NAS low-noise are the same things that make a streamer low-noise - the point is that you leverage a lot more of the benefit and value by using it more directly as a streamer than just as a NAS. This applies to Sense app too, its much less involved if you're not using it for playback control when it's only a NAS.
These days, the better way to think of it is to have a very good-sounding streamer that may, or may not, have optional storage built into it. Our approach is that it's actually better to have the storage within the player/streamer than have separate network transfer from NAS to streamer; storage management is more efficient, latency is lower, network noise reduced etc. This is basically what our newer products with respect to the modular approach of fitting your own SSD, not to mention they can be ordered without audio output modules if you still only wanted to use as a server.
