It might amaze you but basically this same question was asked just yesterday:
Importance of streamer in audio chain
And it's been asked before then, too.
Aurender ap 20
I am going to purchase this unit. I recognize that separates are preferable,however I am space challenged, with that predicate established, would I obtain significant improvement from a standalone streamer? This is a secondary system, streaming will be primarily source, needs to be very good, not reference
