@jw944ts This is a very common problem which affects the majority of systems occurring with female voices, violins and woodwinds. Stuff with a lot of output in the 3-4 kHz region. The BBC developed the BBC or Gundry dip to handle this problem. It attenuates the frequency response in this region I believe it is by 3 dB but I could be wrong. It is in this region that our hearing is most sensitive and where many rooms are most active! Speakers that disperse widely and rooms that are not well treated are by far the most common protagonists. Is it possible that a recording could be the culprit? Yes, but highly unlikely. It is also possible that a frequency response aberration in the speakers themselves is the problem but good designers are very aware of this problem and try to avoid it. Many people do not even realize they have a problem and think this is the way these instruments sound!
You can buy Acoustic Foam Tile online for peanuts and experiment taping it up on walls in various locations before you spend a lot on room treatments. Many people will initially think a properly treated room sounds dull. In relation to what they are use to listening to it is relatively dull. The high frequencies are well localized instead of being blasted around the room by one reflection after another.
