While my EM3pro's were being manufactured, I also sent to earsonics my sr-001mk2's. They were interested in experimenting with the possibility of making custom eartips for them.
Sadly, after looking at them, they told me it was not going to be possible bummer!
I think it cannot be to difficult, next I will try ACS, Im not giving up!
I auditioned the EM2 Pro a few months ago but was not especially impressed by them, i can't imagine any IEMs being as good as the SR-003 i have, from a technical standpoint at least.
I must say i'm enjoying my SR-003 even more than my LNS somehow.
