If it sounds sterile and lifeless you know it's working correctly.
I have noticed that the brightness isn't what makes it fatiguing, it's the harshness that's the problem. Most of the harshness can be solved with power conditioning, but the problem with 44.1 kHz remains and it still sounds a little harsh and lifeless. HD590 and K501 now sound equally bright/harsh but K501 is
less fatiguing because it has a more balanced and transparent sound, but without power conditioning it was the opposite.
Comparing the DAC1 to Cary 303/300 (with K1000) at 44.1 kHz I find no difference in harshness at all, it's just supposed to sound like that. But increasing upsampling to 768 kHz makes it sound super smooth like with tubes.
A DAC that doesn't have enough speed to show 44.1 kHz correctly (or has a better power supply) will sound smoother, and in most cases, better.
If I would buy a DAC now I would choose one with upsampling, but the first time I tried upsampling in my system it sounded brighter, thinner, colder, lifeless and more fatiguing when power conditioning wasn't used (the same symptoms as with DAC1). But not anymore! Power conditioning added lots of body and warmth.
K1000 used to be my brightest headphone (horrible), but now it's my warmest and least fatiguing headphone. Power conditioning does weird stuff...
DAC1 with a tube amp would be the cheapest way to smoothen it out and make it sound more like real life. For 44.1 kHz I need tubes, but for 768 kHz I don't.
Conclusion: A component can be worst in one system, and best in another.
