Streamers - Auralic, Aurender, Lumin, others...

@lanx0003 Qobuz isn’t available in my country so that’s not an issue. In fact, I’d probably use it as a Roon endpoint and only from time to time the native app to stream Spotify. Have you had a chance to compare it to other (more expensive) streamers, maybe?

@jjss49 Makes some excellent points about clocks and noise, switches and isolators but the most important thing is to get started . Pick a solid manufacturer with good customer service that's going to be around for a while. That's more important than worrying about getting the 9th degree of resolution, which can be achieved through cables and other means. However make sure you get a streamer with a clock input . 

Regardless of the connection the streamer makes a huge difference. It is all about power management, electrical and mechanical isolation as well as circuit design,. You have a good DAC, you need to mate it with an equally good streamer. My rule of thumb is that the investment in your streamer should equal you DAC which should roughly equal the preamp and amp. Each needs to be painstakingly researched an chosen to be in the right sound family (one you like... mostly DAC, preamp and amp) and compatible with each other. I came to this conclusion over time when I would upgrade different parts of my system until they where they seemed compatible and synergistic with no component holding the other back and the investment level tended to be in the same ballpark... For my main system today this is true for my main system all electronics as well as my headphone system.

So, research and invest in a great streamer.You will be happy you did. 

Gonna have to respectfully disagree with random formulas for allocating your $ to a streamer.  Do your research, follow advice that makes sense to you for your system, and save $ where you can.  Good luck!

Doesn't sound like we disagree, but have different priorities.  I am trying to ring out the maximum sound quality possible at a given level... not to save dollars. So, we have different priorities. Makes sense.
