    An interesting find.

    SO I found this today in the classifieds not knowing exactly what it was for about 10 secs. Then it hit me. If I not mistaken, is this box essentially a safer way to listen to headphones of all impedances on a speaker amp? Or am I misinterpreting this things use cases?
