SM64

No, not the Nintendo Super Mario 64. 

EarSonics is replacing its SM3 with an upcoming new model called SM64 - three drivers, three ways, but interestingly with what they called an 'impedance corrector' in the crossover circuit. Is it the same kind of circuit used by TDK on BA200? Hopefully yes, as it will make the IEM much easier to pair with different sources. However, with impedance as high as 112ohm, I don't see much of a problem anyway. Yes it is on the higher side of things, but sensitivity is very high as well, so typical source like iPod should drive it loud enough.

From my audition of SM2 and SM3, EarSonics tends to sound way too laid back even as a stage monitor and totally out of my preference (and I do have a fairly loose preference for a person who collect IEM). Well, If SM64 carries the same house sound, I am not sure I'll like it either.

Oh, no price yet.
