Thanks for a great review.
These are pretty relevant to me. My Westone 4's, bought more or less by chance really turned me on to IEM's, and I'm contemplating going for customs.
I've been pondering the Miracle, but sending a mould to England takes time and is not as effective as getting a fit in Norway. I'd be very interested in a comparative review with those IEM's.
I do think that if the S43's are within 5ish % of the other similarly priced customs, I'd probably go for the S43's due to the ease of the producer being situated in Norway.
Wonder if I can get a test-listening from them. Have to investigate this further, I guess. Anyways, great review, thanks a bunch :)
