Although the OP already landed a different unit, I wanted to address an unanswered question.
The Aurender A15 is essentially the same as an Aurender N200 with the addition of the DAC. It uses the same streamer/server components and power supply designs of the N200, and I was told by Aurender that if I ran a signal out digitally from the A15 bypassing its DAC that it was equivalent to running an N200.
