Hi Julian,
I guess I was taking a risk with the new headband, but because I've a smallish head, the extruding part of the Staxs headband stuck out a lot, which provoked some comments from some that have seen me with them on, so a different headband is something I've been after for sometime.
The thing that concerned me the most though, was whether there'd be a change in SQ, but after Ian popping through with his 009's, I'm pleased to say they both sounded the same. Once the foam and black leathers been put on, I'm confident the comfort will be spot on, plus for me the leather will enhance the looks.
I owned some 007's and was happy with their headband because it doesn't stick out like the 009's.
I can't say my ears have got hot while wearing the 009's, probably above warm, but even then not very often.
I've got a Stax headphone cover which is on my 009's when I'm not using them. However I think I'll look into two glass domes to cover the amp section of the BHSE and Aristaeus when I have it. The BHSE's amp section is on the top shelf of my audio rack and the Aristaeus's will be at the side. So while I'm very careful around my audio gear, accidents do happen, putting glass covers over them will be extra insurance so thank you for mentioning that.
Sorry but I've never heard of Rammstein, but I'll search for them on the internet and have a listen.
As you know I tried downloading Audirvana + but was unsuccessful, but when I'm ready I'll be giving it another go.
