I don't think it matters to most young people anymore than owning a high quality watch would to me.
My son is 24 and my daughter 22. They both like their expensive watches and their fashion conscious iBooks and iPhones. My son is interested in decent sound but my daughter listens on here iPhone or iBook speakers. She can't even be bothered to plug in here Logitech 2.1 speakers.
My son is more interested in 5.1 that stereo. I find the 5.1 impossible to listen to - it sprays sound all round the room and with my high frequency deafness in one ear I just get totally confused. I stable stereo image from an analytical system I find easy and enjoyable to listen to.
She really has no interest in the reproduction despite her musical bent. I suspect she may enjoy music more than I do.
Musicians are a strange breed. They will either choose a no nonsense quality system - Quad and Harbeth would fit the bill, or they don't care about the quality at all. I suspect that is because they are not hearing with their ears at all - the poor system or radio on which they are listening is just a memory prompt for their mind's-ear - they are listening to another or some ideal performance. The best of them would achieve the same end by reading the score.
But back to the young. It is driven by fashion. Get the right audio monitors into the Apple Shops and you might start a bandwagon rolling.
Ah. A friend of my son's (another Engineering Graduate) has a rich father and is earning mega-bucks in the City himself - he has a top of the range B and O AV system with the speakers that look like Daleks. Fashion, but also extremely good audio.
