Just replaced my computer’s old Logitech Z323 2.1 (stereo plus subwoofer) computer speaker setup with a small stereo amp and two small bookshelf speakers, and even just half an hour in, with hours to go before the amp and speakers are really performing at their best, it’s already a noticeably better sound. Fuller and more well-rounded, and as a bonus, not having a subwoofer sitting on the floor of my office means I won’t bother my wife downstairs nearly as much. Well worth it!
