FYI, I own a Node and the Denafrips Ares II. If you use coax or optical into the DAC you can use the volume control in the Node software. If you use USB (which is for sure a better connection between the Node and Denafrips, look this up) you'll need a separate volume control. I use the USB connection and a pre-amp to control the volume. I've found that whenever I tried to go pre-amp less the sound was simply not as dynamic, full, or engaging. YMMV.
