@robwilgus - I have a Pioneer XDP-100R and Questyle QPR2. I use the Pioneer XDP-100R for the Z06 because it has WiFi & BT capability. I use the QPR2 (not WiFi or BT) for my Focal Utopia headphones in my office because I like the balanced output and better SQ from the QPR2 DAP. Either DAP is amazing. I also use the XDP-100R when I am listening on the enclosed glass porch with my Bose portable system w/ remote control… that DAP is more for on the go… I use it when washing the car, out in the back yard, on a walk… the Bose is very portable and sounds amazing for essentially a remote speaker… options are very important with this full contact audio sport…
