I agree with Charlesdad…. If you stream a lot , the Streamer is very important as it is akin to a CD transport. Can you imagine pairing a $5000 DAC with a Coby DVD player as your transport? It will work but you just inserted a major bottle neck into the digital chain.
I also have a Bluesound Vault 2i and it’s been great. It has so many things going for it , including convenience
When I turn my TV on the Vault senses this , puts its input to Video and I now have. Control of the volume for TV and movies
Tons of free content. On and on.
But when I really want quality over convenience I power up my Aurender and Stream Qobuz or Tidal
Those streams sound good on the Vault but the Aurender is noticeably better in every metric.
