I think the best thing about my "rig" is that I can listen to it for hours and not think it needs to be better somehow...I don't listen to my favorite music and think, "Should I reverse the fuse? cover the walls with foam panels? look up what Nelson Pass is thinking about? buy tube dampers?" Nope. I might swap out something someday just for fun or if something dies, but for now...it's utterly dialed in to my tastes.
