Re: Bah!
I have a pair of Dynaudio accoustics professional active speakers, all analogue, and I can assure you, even at your age, you *would* hear the difference. The industry rips people off with incredibly expensive consumer range speakers and amplifiers and Joe Public is lead to believe they need to spend £10K on a good system.
Most people haven't got a club what decent sounds sounds like, and it doesn't have to cost the earth, you just need to know what you're doing.
