You can train yourself to ignore the cringing, you can soften them with soft amps, you can use ultra clean components all the way through to give them the best signal possible, but that peaky behavior is going to be there to a degree, it's the nature of the headphones. I am fully expecting that to be addressed with the next iteration of the HD design, as let's face it, it is by far the most voiced complaint against the HD800. In fact, compared to the complaints against this, there are no other complaints!
You watch: if the ringing/peakiness is addressed, there will be some who say that there is not enough detail! In 30 years of business I know there always will be complainers. And in 30 years of working with audiophiles I know for sure that getting rid of the peakiness will be perceived by many that detail is lower.
