Well said Luminette
I agree that it is excellent of ultrapaul to investigate the possibility of addressing this issue. The majority of manufacturers will simply shirk responsibility if any modifications have been performed to their product, as this is the easiest and least costly stance for a manufacturer to take.
But considering the nature of the customer base here on Head-Fi, we are a customer base that greatly values customer service. And word of mouth counts for alot in our community. Exceptional customer service garners intense brand loyalty, which gets passed on through all the "reccomend me a headphone" and review threads we post.
If Ultrasone were to continue to warrant headphones that have been recabled or modified - perhaps only from a list of certain technicians, or other criteria - they would stand apart from the pack by more than their sound quality. And I think this would have a very positive impact on their customer base, both here on Head-Fi and elsewhere.
