I apologize if this question has been an answered elsewhere, but if it has, I have not found it. I am the happy owner of a Z kit one that I built earlier this year and would dearly like to try it with headphones. Ideally, I’d like to be able to build an adapter that I could connect to the speaker terminals and then to a headphone. Does anybody know what it would take to do this? my headphones are Sennheiser hd6xx and they are 300 ohms. I also have a pair of hi-fi man HE – 4XX, which I believe, have less resistance, but I’m not sure how much exactly.

Thank you! Just what I was looking for and more. It also looks like a very interesting channel so thanks for that too! Have you tried this design?
