Nice! Have been thinking about the selector for a while… now I think I know its purpose.

Thanks for feedback. Those diaphragms in the picture were much more stretched then the previous I‘ve made. Seems I’ve to keep on trying to make diaphragms with the right tension.

I’ve retested and I got about the same results. Also tested a pair of SR-007 mk2 and then I got graphs more like your Orpheus Clone and 007mk1. I’m very satisfied with the bass, well not as good as 009S but good for my DIY headphone. I’ve tried different diaphragms and some of them are terrible, but I actually manage to do some better. Another thing is that my home made phones are not as sensitive as Stax and the diaphragms need time to charge. They start soft and after half an hour or so the sound reach it’s max. Here is how I stretch the Mylar film. 12 inch inner tube and Scotch Magic tape.

Wow magnificent! Nascent Audio?

Happy Birthday!

Today a miniDSP EAR arrived. Have made some measurements and I got the below graphs. I just followed the manual but I'm not sure how to interpret the outcome…
