I spent a good amount of time reading this thread and there appears some negative comments are often expressed about the HD-800.. those being bright, having a treble peak and even sibilance.. I don't mind slightly bright, I am good with that and might actually prefer it. Further, I am not against using a tone control or EQ. However, severe high peaks and sibilance are another matter and unacceptable to me in any headphone (or speaker) of any price, especially an expensive one. Sibilance is just plain annoying at best.
I listened to the Audeze LCD2 for the first time at DECfest a few weekends ago and determined I needed to move to a top tier headphone from my current selection.. I thought the HD800 and LCD2 or LCD3 to be likely candidates, but hearing these comments seem to eliminate the HD-800.
Are these legitimate concerns or overblown complaints?
Here's my advice, if you're not going to get a really high end amp, get the LCD3. If you do plan on spending a lot of money, the HD800 will scale higher than the LCD3, and it's only a matter of getting the proper match.
The LCD2 is quite a bit lower level than the HD800 and LCD3.
