The Naim streamer is hard-wired directly to the router (ethernet)
I have not tried DSP but Im not sure how I'd try to tailor it to make the sound less hard, and get the ambiance back. I only have one room I use it for, my main listening room which is my living room.
Problem with the trial period is you have 14 days to figure it out and keep it or get rid of it. I ran out of time, but went back twice to listening tests and both times was not enjoying the result And as much as I like the way it integrates all my sources and services, the name of the game is maximum listening pleasure.
