The channel islands box will work fine. You end up having an EL34 based headphone amp. If you want to play with one, I have the same thing by another company that I'd sell wayyyyy cheaper than $150. They work great. Has volume and speaker on/off. You just need a short pair of interconnects. I can throw in a pair of those too?
