A lot of head amps sport a Through out switch which cuts the head amp and you can listen to the other thing you want to listen to.
Adding headphone amp with no fixed out (preamp)
My new linestage is coming today and I’m excited. They also make a highly regarded headphone amp but it seems like there’s no way to run both without having to unplug the sources and plug them into the opposing amps.
Am I wrong or is my ignorance in headphone setups showing? Ideally, I’d like to just route the signal to a headphone amp and then listen.
