Some great advice given here.
Here’s a “self centred” description of my own streaming journey, hope it’s useful @Gigantor 
I do find streaming useful for new-to-me music, some of it is even new new music!
I sometimes follow an artist’s journey through time, listening to their output in temporal order, something that isn’t impossible with physical media, but would certainly have cost and media storage implications.
I also still buy physical media, vinyl and CD. Buying a mixture of music I’ve heard before and some I haven’t; I still enjoy the anticipation if I haven’t heard the music before and I settle back to listen to an album for the first time.
I’ve recently subscribed to Electronic Music magazine, and similar to you have used it as a means to discover new music, for which streaming has been incredibly useful. I can easily listen to most of the featured artists and releases without having to buy physical media.
I do think you would find having streaming available as a source to your hifi both useful and enjoyable, in addition to your vinyl and CD front ends.
How to do that though?
I progressed as follows
- Chord Mojo mk1 DAC, fed by my mobile phone
- Chord Hugo mk1 DAC, fed by my mobile phone
- Chord Hugo mk1 DAC, fed by a Primare NP5 streamer
- Chord TT2 DAC, fed by a Primare NP5 streamer
(Mojo now with a friend on long term loan. Hugo on headphone duty)
I kept my Naim CD5 throughout. I upgraded my TT during that process from a Systemdek to a Technics SL1200G. The relative performance of the streaming setup started off better than my CD5, but not as good as my vinyl front end, to where it is now, the TT2 sounds incredible, some things I prefer it on, some things I prefer my Technics. I’m happy that they’re more or less equal.
I write all that as I do think the quality of the streaming source is important to evaluate. Do you want streaming just to help with new music and don’t mind if the quality isn’t up to your other sources, or do you want a streamer to be equal to, or better than your existing sources?
You could have a great sounding streaming source, to help with new music discovery, but possibly not as good as your CD/TT, for the fairly low entry price of any one of a decent number of DACs, feeding it with your mobile phone, or computer. And frankly, entry level DACs, if the Mojo can be classed as that, are ridiculously good.
I get the desire to stay with Naim, and the argument for simplicity (DAC+phone/computer isn’t as convenient as a ND5XS2/NDX2 for example), just describing my own journey if it helps!
I always found the Mojo and Hugo mk1 a bit of a faff. The TT2/NP5 setup is the most convenient setup I’ve had, remote controlled, and is now more or less as convenient as a dedicated and integrated streamer/DAC. I do listen to more streamed music as a result!
Best of luck Mitch
