Mine get here today, and, will be a "production" unit. IFF CJ impression posts are made, can we agree to tag those as 'pre-production', even if there is no, er, differences?
I will refrain from posting anything for a few days, mainly because I believe in breakin, and am using an altered (balanced) cable, as well as an aftermarket (again, deferring comment until it all settles in).
I will NOT baseline SE, as that is just a waste of time, for me.
