i dont really get his dismay over people "cloning" the RA-1... its just a simple op-amp based amplifier? any CMOY is the exact same thing? every op-amp datasheet has a nearly identical circuit for as long as i can remember as one of their "example" circuits...
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
