I recently heard of the Axxess Forte from Audio Group Denmark (Aavik, Borresen) that may be all you need for a second system at half the price or less than the AP20 and may be worth a look. Best of luck.
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
