Women have better hearing than men. They respond to high frequency distortion and high noise floors immediately. Unless, the music is presented without harshness and digital edge, they do not respond to the music.
So, changes in your system have probably not decreased the edge to music, but the recording mastering has.
My partner of 37 years has accompanied me on trips to high end stores and listened to my system. Until my current system (under my UserID) has typically responded poorly because of the high frequency (SS) hash and distortion. A really bad recording will still send her running… but only on <1% of recordings. The all tube system, that emphasizes musicality is forgiving enough for even a women to enjoy.
