although i do understand if his issue is people selling "RA-1 Clone"s since that is his trademark, but people "cloning" the design of the RA-1 is kind of silly... then every commercial manufacturer that uses a simple dual channel opamp stage for their headphone jack copied grado's RA-1?
anyway, this thread was a great read, nice to know that grado's people are as nice as their products
Pardon this mistake (if it is, I read the interview a while ago) but I don't think John has a problem with people making the "RA-1 clone" for personal use. Like you mentioned he doesn't want people selling them labeled as such.
