It's all psychological. And physiological. I'm glad this group understands that because other forums are slaves to marketing and marketing terms. If any of us played in rock bands in our youth, we all have varying degrees of hearing damage, anyway. What might sound bright and sparkly to a 17-year-old might not sound so harsh to my weathered ears--after years of loud rock and riding motorcycles. Besides, every other component affects sound so much, how can anyone say "this amp sounds like this." Change the speaker, and you have a different sound. Mic the amp at a venue with a cheap PA system--different sound. Change some pedals in your board, different sound. I'm glad everyone is moving past the marketing trick of pouring $2 wine into a $200 bottle and convincing us we have a fine wine. Switching back to a Fender valve amp this year didn't make me a better player, either. Although I REALLY wish it did.
