people say they are more refined I dont know what that means
I think your listening descriptions show that you DO know what it means.
You said:
it’s definitely all in the midrange….just a tad not bright but just a little more that I don’t get with the Forte IVs
I just cranked the song Black Day by Monolink a very dynamic song, cracked it way up and was clean and I just let it go…the Fortes didn’t sound good way up there to my ears…..
You're hearing exactly what you're describing. The upper mids and highs are NOT making you cringe and you're NOT getting fatigued. Extra volume is equating to extra fun, not "turn it down."
That's, at least, a partial definition of "refined," as I understand it.
Good job!
