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.

Do different streamers really sound different when using an external DAC

How much difference in Sound quality can be expected from different streamers?

Streamer Comparison and Suggestions

Does the streamer effect sound quality

Surprised by streamer differences

why expensive streamers

Point of higher priced streamer?

Another post about a streamer upgrade

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.

we  would agree that streamers can  make a very audible difference and in our opinion thea20 is too expensive for a product that cant be upgraded, or improved upon as technology continues to evolve., so we would pass on it 

We did a shootout of our 432EVO Aeon vs the aurender n20 our Aeon server sounded better, and also comes with a built in cd ripper, as well as a modular and upgradable platform and is a full Roon core as well.
