I used it to feed a Pass X250 via balanced outputs driving B&W N802. It is clean, I used internal jumper -30dB setting so that at 12 o'clock volume, it is about right listening level most of the time. I used passive volume control for about 20 years to get clean sound but can say with confidence that the HDR gives up nothing on clarity and restores all the dynamics that were lacking in my previous passive setup, much to my surprise.
