I've been doing a good deal of searching and haven't found a reasonable solution to this. I live in a shared house so I need to use headphones (sens hd590) when everyone is asleep and so on. Anyways, I was interested in picking up the Swan M10s but unfortunately they lack a headphone jack. Can anyone recommend a decent amp or another way to use headphones without excessive unplugging and replugging of the speakers and headphones? Any help would be greatly appreciated. Thanks!
