Once again, response above 20kHz may only be really relevant to the sound in the case of global feedback and challenge of compensation of the feedback loop for the the stability of the amplifier.
I have used all of these transformers at one time or another, but never compared them in one amp with no changes. My opinion is that there are much more important issues in amplifier design than a few Hz or kHz of response at the limits of the audio band.
