So your path is very similar to mine (and many others here)...I elected to keep my system vinyl centric and am putting my streaming system into the room we entertain the most in....I started streaming thru an AVR system to understand what was out there... I settled on Qobuz... from an equipment perspective I elected to go the Bluesound route as many others here have and recommended ($599)...the main resons for this is that the user app is very similar to the mConnect app I use now, the set up is very easy and the performance is very high given the price point above...should u feel the need to upgrade later, u can still use the Blusound as a streamer and connect your upgraded DAC thru it...
Good hunting, I had a blast researching all the variables and the folks here are very helpful
