Have those speakers ever sounded 'less/not harsh' in that space?
Do you have tone control anywhere? Tried cutting treble some?
You might consider trying tone control first, even temporarily, and find it's the speakers in that space are simply too bright, not the amp at all.
Some new equipment has tone controls with bypass.
Anything, especially these days, having a return option after listening in your space is important.
If a new item has no return, perhaps consider used, i.e. eBay, with return option.
