@gkelly Thanks for the input. Curious why you use the AES/EBU input instead of USB when USB on both the Pulse and the STR has better specifications?
I have corresponded with Innuos and am leaning towards the new Stream1 and Innuos suggests USB as their preferred output to my STR preamp.
They also suggest that to match the Pulse performance, I should add the LPS1 and to surpass it, the PhoenixUSB board. Those options add up fast but I can swing it if a benefit is really there.
Thanks again.
