When JH3A first announced, I really thought it was one of those brilliant idea that the IEM industry needs to push forward the technology. But today the sad news is, it will not be JH Audio to do it. The idea of active crossover came to Jerry Harvey a few years ago when he was still the owner of UE. Naturally he went ahead and patented the idea under UE's name - with that patent granted to UE early this year and a possible lawsuit if JH Audio decided to continue the JH3A, Jerry had to back off and redesigned the whole JH3A into something without the active crossover (thus the big reason why JH3A's release has been delayed for such a long time). In any case, I am not happy to see JH3A becomes something that is no longer a JH3A. But there isn't much anyone can do at this moment.
R.I.P, JH3A, for what you were meant to be and a dream short live.
