Thoughts and suggestions please

@ronboco 

There’s a USB A input on the back of your N130. I have a 4 terabyte hard drive plugged in.  Works like a charm for storing and playing all my music.

All the best.

@hilde45 There have been e few suggestions to create the text doc so I will definitely at least do that. One thing I don’t understand is if I wanted to switch to say tidal and import my playlist from Qobuz how does a high rez song from Qobuz remain the same high rez song from Qobuz when it goes to tidal? 
 

@curiousjim I would definitely look at the usb on my N130 but I don’t own any songs on my Qobuz playlist. That’s why I am looking into buying them so no matter what might happen to the service I would have my playlist forever. 

I only play purchased digital files stored locally. I update my back up hard drive monthly if I have added new music. 

https://www.tunemymusic.com/ will help you move between services as well as download the playlist in something that MS Excel can understand.  There are a few others, none of them are expensive.

@ronboco there’s software on the market that transfers playlists.

One such example is Soundiiz in a very unlikely event you would need to use it. I would not purchase the tracks though at least until there are some indication that the service is going out of business  

As to streamers….I’ll tackle this knowing the possibilities with your 866 inbuilt DAC. 
The Boulder amp does not accept USB audio so you have to work with a streamer that features AES/EBU and or toslink. The latter is typically an inferior interface while the former requires a streamer with very good internal clock. Your other option is Ethernet input that allows the 866 to be used as a Roon endpoint. 
Given the Boulder internal DAC is an option that adds $1500 (may be more now not sure), getting a streamer for $5,000 throws your system out of balance. 
 

I think I suggested this to you in the past…try Roon free for couple of weeks. It requires a roon core that you would install on any computer that’s sitting on the same network as your 866 and you can control your music with iPad or android tablet. If you like the sound, you can keep Roon, pick up Roon Nucleus One (that’s their dedicated core) and mount a 2.5” SATA drive inside the Nucleus. You can purchase your playlist if you want or you can save your Qobuz playlist as your Roon playlist which saves the track metadata meaning you can just restore these tracks from Tidal for example. Some food for thought. 

If you insist on getting a new streamer you can look into Lumin, Auralic and Innuous. These offer usb in for external storage.
Aurender in a $5000 price range has nothing with AES out. There are other options as well on new and used markets.
