I have what I like to call my Super Duet Power Center. I have my HeadRoom Micro DAC on one side and my HeadRoom Micro Headphone Amp on the other with PS Audio Noise Harvesters on the spare outlets on both sides. And if that weren’t enough, I have a 3rd Harvester in the spare outlet in the wall. BTW HeadRoom gear I own has been discontinued for years. The amp has a “crossfeed” circuit that I’m not going to go into, but it makes headphone listening sound much more natural especially when listening to heavily panned rock music. If you use Foobar2000 there is an add on: Meier Crossfeed that really works well. This is for headphone listening only.
