I am not sure why you feel the need to debate, I was giving specs that might help the chaps query, not regurgitating specs as you put it.
You had one very important spec wildly wrong which I corrected because it might help him, frankly it was so wildly wrong might have just been a typo for all I know, either way I wanted the guy to have the right information because being out by a factor of 10 seems worth correcting to me.
Sure this is the Campfire thread but it is the use of IEMatch that was being commented on and the specs that go with that and there are plenty of other highly sensitive IEM that are over the 12.5 ohm impedance minimum recommendation. An IEM doesn't need to be low impedance to get hiss, high sensitivity and more conventional impedance of say 16 ohms or more will pick up hiss badly also.
Low impedance isn't a prerequisite to picking up hiss either, I have 10 (all) BA set that are 5 ohms and fairly normal sensitivity that pick up very much less hiss then the higher sensitivity and higher impedance Solaris.
Hopefully you don't see anything worth debating here, that isn't my intention.
