almarg, curious about a response of yours. You indicate that in the case of the GET Triton One's the amp wouldn't be a good match because (paraphrasing) the higher amp output impedance and the speaker’s variation of impedance would be an under-emphasis of the mid-bass region, and excessive brightness in the upper mid-range.
Why should the impedance mismatch yield any different sound characteristics in the T1s than if it were paired with an amp whose impedance was an exact (no such thing I know) match? If the impedance of the GE T1s are low with respect to the amps "preferred" impedance, this should manifest itself as additional current being drawn from the amp and not necessarily anything audibly undesirable. Granted, to much current draw is itself undesirable.
