Here are my two cents worth for my findings with my IM70 >50hrs at least.   Bass: Slams hard and very physical, not overblown and does not obscure the mids. Mids: Very nice, sounds correct to say the least Treble: rough, it is not the strong point of this IEM to say the least. Lacks air. Soundstage: Very closed sounding to me compared to say, a CK100 Detail: Not a particularly revealing IEM but clear sounding enough for me, greyish blackground that does not work well...
Just refering to the Zana Deux, which is a SET and OTL amp. Low output impedance is achieved by global feedback(nfb) or else it would be 90 ohms. So SET and OTL are not mutually exclusive.   OTL and OCL are more of the coupling methods used to achieve blocking of DC from getting into your headphones. Zana Deux for example is OTL but is capacitor coupled to achieve DC blocking. Transformer coupled tube amps are generally OCL.   I think push pull is best explained...
Probably the knowledge, especially with regards to which distortions weigh more on the human hearing, even now its not really known. Soundstage IME is a very real thing though, imo phase and harmonic distribution has the most to do with it along with other factors.   I tend to think that some designers would focus on a few electrical parameters they would want to optimise and see whether it sticks in the subjective listening experience as there is a lack of correlation...
Read the graphs on THD+N vs Max output power, specifies power for 15 - 600 ohms. 
I feel slightly guilty for missing the chance to try them a few weeks back, especially since I was pretty excited about it since the beginning. Kind of wondering what kind of monster we helped in creating.
  Don't be stupid, if you add a few db of bass to TF10s already bloated bass, of course you will get distortion(TF10 by itself already has a long bass decay)! EQ done correctly as others have noted can help to really improve fidelity and can help lessen stored energy issues. Certainly not the cure all but a valuable tool.
Nice! I think I took a lot from this. 
Probably the biggest was 2009, 30 was the size of the April one. Though officially about 15-20 showed up.
Will be bringing along my Pioneer Monitor 10s(2 of them), SRH840 and HD800s. May be also bringing the HD25s and for amps, the AMB M3 amplifier(estimated to finish building by early, mid July). As one member has mentioned, there was a meet held in April already. Also there is one mini meet happening at June. So August would be perfect. Also by then a few of my friends as well would have finished building some of their amps to bring a long. 
Thanks for the help!
