That's how I feel. His choice of words are the type of descriptions that I would use to characterize a type of IEM that I would consider and put on my list.
Like you said I will wait out on other members impressions before getting too serious about purchasing.
Isn't there a delay in order to replace the casing? I haven't kept up much with the SM3 appreciation thread but I think I read that the new housing could cause a slight change in treble? Or am I pulling that from something else. Either way if I wanted to buy it I would still have to wait. So this'll give me some time to think about it. Plus the only feasible way I could obtain a pair is to sell of my MTPCs which I would need extremely strong convincing from the MTPC -> SM3 converter's camp (there's a few of them, which is why I'm even considering these; there must be something to them) on the tangible improvements from one to the other.
I have confirmed with Franck, it won't change the sound. They just reshell all their SM3 in stock, by using an improved formula for better ultrasonic welding.
