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. 



I think there may be a bit of confusion here. All the streamers with volume pots or software volume,  only controls the analog out volume.  I am not aware of any that that controls the digital out.

My research tells me Allanblissett is correct. The streamers I investigated appear to have fixed level digital outputs. I don’t know if other responders know otherwise or didn’t read my post carefully. It's an unusual circumstance. 

Seeking clarity has made me more confused than ever. 🙂

The Node connects to the GaN1 through the coax digital output. The volume control is in the digital realm. Not sure about other streamers. The GaN1 has no analog inputs and only speakers out.

Maybe the Bluesound is the only one . That's why it is featured  with the GaN1 on the Peachtree site.

I’m curious.  The digital volume control on the Node is likely crap and drops bits when using its analog outs, but if you’re using it strictly in the digital domain going direct into something like the Gan1 does this become a non issue?  If so this seems like it could be a really elegant and effective solution for a budget/compact system.
