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.

Lumin absolutely does variable volume control on digital outputs and has maybe the most advanced algo available. I have the U2 Mini, it is a streamer only (no DAC) and it has the Leedh volume control. It's excellent. 

Have upgraded to Auralic Aries G1.1 into Peachtree Gan1 RicEvs modded. 
Absolutely Amazing.
