I think I might know why but was curious to see if anyone else had an opinion on it assuming nothing was wrong with either amp.
Ahh so this is a question harking back to a land long ago and far away where one could legitimately worry whether a Dual Showman with JBLs was loud enough. Those were the days....
I think it has a lot to do with where the lead guitar fits in the mix. I think Marshall got it right in the golden age of rock, focusing on the high mids, which can seem too trebley outside the mix. Power in the lower frequencies is pretty much wasted as you are fighting with the bass player and drummer.
Later on, guitar started taking more of the lower register which pushed the other instruments even lower making it hard to even distinguish the notes. I remember a bass player taking a solo and you couldn't really hear the notes but you could feel the pressure waves. I think that's why there is a lot of emphasis on high frequencies for bass players in more technical music.
If you ever get a chance to hear a well known artist or group recording that is split into tracks, the guitar(s) are usually pretty bright.
Especially Marshall tones.
But when we play at home we want a fuller tone because a too bright tone is obnoxious alone.
