I know, custom IEMs can be frustrating, can't they?
Still, I think when one eventually gets a successful fit and sound, it all becomes worth the pain!
I've learned to relax with the waiting times of months, and just... wait... all will be well in the end, even if it's not with the CIEM one originally thought it would be (I mean that from personal experience, not directed towards your SA-43).
Joe really respects the SA-43 and I really respect his opinion on CIEMs, so I expect the SA-43 sounds wonderful. I hope it brings you much pleasure when it is repaired and re-fitted for your ears.
The fit is partly my fault, as i didnt use a biteblock when getting my impressions done, and my problematic earshape is another - the right Ciem got sanded down with the other refit i had, but there still a tiny bit of discomfort on the right, and it should be as the left, where there is no problem whatsoever..
I have been using my Itouch and thats my only device, and i aswell respect Joe's opinions and i can hear myself that my SA-43 needs a quality companion to reach its best, and thats what im trying to get sorted too...
i am very sorry about my wallet, but u know the drill :)
