Most harsh/shrill sounding speakers (vintage)

I got the speakers I have now, which blew me away in the store.  I took them home, purchased a new Adcom amp and pre to go with them, and it was absolutely the worst sound I have ever experienced (great detail, but so harsh certain types of music were unlistenable)--took them back, found I couldn't live without them, went back and re-bought them, figuring I'd find a way to tweak or live with the sound--after a couple of years, I bought a cheap tube amp on a whim.  Those speakers went from the the worst to fantastic and I haven't touched that system in more than 25 years.   I have no doubt that the tube amp 'degrades' the signal; but whatever it does, my ears are grateful.

I had some Klipsch Khorns.  At high volumes the highs were harsh, and the bass made you sick it was so boomy.

@jdane What are these speakers?

Yes sorry for not making it clear in the opening, this topic is dedicated to hifi speakers. Hence why I mentioned the Yamaha NS-10. They do sound fantastic in a well treated room though. I wanted to see if other speakers in that category and in the vintage zone might be available at a low price given that people dislike their sound out of the box so much. Studio monitors often are disliked for their sound because people don’t know how to use them. But the Yamaha NS-10 horizontal studio monitors sound absolutely great. No mistake. I mentioned they sound like crap because it’s their reputation. :)
