You can spend as much as you like on speakers and amplifiers, and still have your sound held back by pesky old physics.
Very few of us live in recording studios, and many of us can’t or don’t want to start putting carpet on the walls to get the same sound-dampening effect. Most rooms that are home to decent speakers have no sound treatment at all. If you live with a partner, you may well be lucky to be allowed those speakers at all.
