People who really love listening to music and have heard a decent system are not going to settle for MP3 files. It is a matter of priorities.
Those same people who are looking for cheap used stuff on e bay are buying $10,000 snowmobiles so they can run around going no place burning fossil fuel or 75 inch TVs with tiny little speakers. The people here would rather buy Hi Fi gear. The trick is not just building a cheap system it is building a great system inexpensively. No offence n80 but the stuff you are talking about is not even remotely on our radar. If that is all you can afford than go for it. And, if you really love listening to music you'll get a good job, save money, skip the snowmobile and build yourself a great system.
