dsper - They are overpriced because the tweeters are fatiguing
This is the most common complaint I have read about on many speakers. It is important to understand how any speaker was designed and tested (the type of room that was used, and associated gear ) - compared to the room and gear in which speakers are planned to be used.
Some audiophiles like to play roulette with their speakers; keep bringing in different ones, keeping the room and gear the same. Hoping to get a match.
I think the better approach when the high frequencies are fatiguing is to do one of two things.
1) Turn down the treble, or, 2) Turn up the bass.
You need equilibrium and both can be done by speaker room/angle positioning, different amps/preamps, etc...
Just angling the speakers outward a little may be all that is needed.
