There is no doubt I can hear clearly identifiable differences between using MIT terminator versus DNM Reson ICs in my main rig, in particular between amp and pre-amp. These are night and day in design and concept, so I would attribute it to that, an extreme case perhaps.
With most other applications in my gear, differences are more subtle, in some cases minor or not significant enough for me to take notice or care. Like most things, its not a night/day, yes/no thing to answer. Its a matter of magnitude on some relative scale, with differences ranging from very significant to insignificant.
I even believe two fuses can sound different for many reasons, however I do not care enough about it to spend any time investigating. As long as my gear is good and in good operating condition, that's good enough for me. YMMV of course.
