Hi Op...many of us go through this transition.
Or evolution?
I had a Sonos back in the paleo period. Then got an outboard DAC. Then had W4S mode the Sonos , Then got a DACless Bryston BDP for for a streamer. Then on to a ROON Core running on SGC ST. modest Upgraded to cabling. All with nice little bumps in SQ along the way. Sitting tight now.
Its just a personal pref thing but I like keeping everything separate for obvious reasons. Especially with the DAC technology chugging along as it is.
