Had the same problem with my Snell CIV's. I gave tubes a try and got the same benefits. I don't know if I have any ear issues. However, if I listen to any live unamplified music, like vocals, jazz ( not horn ), guitar- my ears don't bother me...
There's something going on in the design of most loudspeakers that opts in on certain measured performance criteria that my ears just don't like. Something to do with performance at the crosspoint? I'm really not sure.
Even some of the best designs with $$$$$ behind them will either do one or two things for me:
1: imagine the most breathtaking image of your back yard on a high res screen, or even a large high resolution photograph. Everything is clear, well placed, multi dimensional, beautiful colors and perfect contrast.
2: you walk out your back door and see what's real.
( the analogy isn't helpful if you have a ton of garbage or a hairy plumber woman neighbor in view throwing rocks around with a
lawnmower, etc )
Lower priced products have the same issues. I find it very difficult to find a speaker that balances my preference in tonal quality with precise imagining characteristics, it's either one way or the other ( and mostly never tonally pleasing) I think that's why a lot of folks dig vintage equipment, classic technology and sources. Many of those products exihibited a tonal quality that has been pushed aside for the pursuit of a measured accuracy criteria, which doesn't often translate to something "musical". Certainly it creates some excitement on the selling floors, just like over-cranking the brightness on big screens.
