... a streamer with an internal SSD slot... Buying one and putting it in is a waste of time because when you burn more music you have to now find a way to put it on the SSD drive that is now screwed into the slot provided by the streamer or figure out how to connect it to your computer ...
I use an internal SSD in my streamer which is connected to my LAN via ethernet. Both it and my PC are on the same network so moving files is simple. I can't imagine an easier way.
