Damping factor will have audible affects. Damping factor = headphone impedance / amp output impedance.
The Senn headphones tend to have high impedance ~ > 300-600 ohms, so they are not affected as much, say if an amp's output impedance is near 1, 3, 60, or even 120ohms. A general guideline is having a damping factor of at least x3-5. The LCD2/3 are low impedance headphones (~45 ohms). Low damping factor (from amps with high output impedance) with the Audezes will make them sound sluggish. I prefer the Audezes from amps with a very high damping factor (very low output impedance.)
I believe the Teac unit you are talking about has adjustable output Z from 16-600ohms. If you maxed it out to 600ohms, the Audezes are probably going to sound "off". 45 / 600 = 0.075 damping factor. That is not good - actually quite horrible.
When I tested the damping factor settings on the Teac amp using LCD2 and 3, it made a massive difference to bass, and less so on overall tonality. On the Senns, not as much difference. But I have no numbers to even compare whether this relates to the points above.
Also, in one conversation recently about a planar magnetic, I heard something slightly off in certain passages, and it was suggested to be the panel resonance. I'm curious if damping factor could affect its audibility.
