As far as I am aware, all Bluesound products can control the volume in the digital domain.
That is the main reason I upgraded to an Aurender. I wanted to avoid but truncation, no volume , nothing to worry about.
Streamer with variable digital output
In my setup, a Bluesound node feeds a Peachtree Gan1 digital amp/power dac. The Gan1 has no volume control and a digital input only. What other streamers have a variable digital output for compatibility with the Gan1?
BTW, I ask out of curiosity. The Node to Gan1 is a wonderful option for anyone looking for two small boxes and one interconnect for less than $2000.
