It is totally logical. There is nothing deceiving about distortion - no distortion at all means input and output are identical and that is the holy grail of high fidelity. Some distortion measurements specs may hide or ignore important aspects of distortion (odd harmonics, zero crossing distortion at low level) but that does not diminish the overal goal of ZERO distortion in a high fidelity setup. This means a high fidelity setup is not going to be audibly affected by a mere fuse - otherwise it is a real pos in terms of high fidelity!
A designer/manufacturer can design primarily for an old 60’s tube sound with archaic technology and tune by ear to decide what flavour sounds the best
or
a designer can design primarily for high fidelity using latest technology and use measurements to prove it by testing the power supply robustness, channel separation, distortion, SNR etc.
What sound is preferable? Well some prefer high fidelity (at the cost that you hear the recording as it was produced - warts and all) and some prefer euphonic glorious coloration that just presents everything in a way that sounds better than the original recording to them (at the expense of robustness, reliability, accuracy and some finicky equipment behaviours from older technology)
