Is it me or new audio gear is too perfect and give ear fatigue?

Speaking of Schiit DACs, I have a Bifrost II in my second system and I think it is a great value in it's price range. With some combinations of equipment I've found it a bight overly bright but currently sounds good.

Hopefully no surprise that it’s you. Nothing wrong with that. Different strokes. But has nothing to do with how theoretically good something is. Goodness is often a subjective determination in the mind of the beholder. But fact is from a pure technical perspective the best modern gear is in general miles ahead of things from the past. Objectively that is. Some people may hate that for whatever reason. It’s all good. We are all different. Personally, I am an Engineer and I value good engineering and find that always leads me in the right direction whereas otherwise it is a potshot. yMMV.

Ear fatigue is caused by higher ordered harmonic distortion that isn't masked by the music or lower ordered harmonics. 

My friend who is an audio hardware vendor told me the same thing yesterday. I was complaining about fatigue using a new product. 

Well yes high order harmonic distortion is in fact a thing to avoid for that reason but if someone really believes ear fatigue due to high order harmonics is truly an inherent problem still in in practice then just stick to tubes old or new and choose your distortions there because truly good modern SS amplification gear is better at that than ever before.

Its like saying fatty food is bad for your health. Yes it is so just find the foods that aren’t. Then make sure to avoid their downsides too. Bottom line is there is more good  quality food that is good for your health available today than ever before. Why? Because people now care about that and science provides the means to make things better.
