The peak to peak difference between 2khz and ~18khz is more than 1 dB. That is definitely audible unless your hearing is damaged in those regions.
I see!
And that
@solderdude and
@Blumlein 88 have liked it, interesting.
So here is a question to everyone:
- the worst case scenario (on the worst channel) is a slow rise to 0.6dB at 10kHz to about 1.2dB at 18kHz. Regardless of other failings of this amp, what demographic can even detect such a HF rise? Or benefit from it, to the point of buying it? (that was the point, if I recall)
I still say a demographic with very very good hearing! don't believe me? dial a 1.2dB parametric equaliser setting at 18Khz (Q possibly 0.2), and test it for yourself.
I am not saying it is beyond audibility! we are talking demographic of people with good or poor hearing.
This amp has multiple serious flaws! this minor, zoomed in FR discrepancy is neither here nor there.
It's like having a go at Hitler, because he was short!
