As much as I'd also like to see those graphs, I realize that the difference in frequency response measurement(bandwidth) on a headphone amp versus a headset(a can of normal dynamic type) is great.
for instance, slight damping errors in the diaphragm cause 'back-EMF' on some headphones which the best test equipment will easily reveal. But ,
On the other hand the typical amplifier classA or AB type would measure pretty linear throughout the audible range in terms of freq. rspce.Doesn't matter if it's opamp-based, discrete, single-ended, lateral mosfet or whatever.
IMO, of course some tube-based units may exceed or fail-to-meet this criteria, depending on their quality.
