Why? That won't teach anybody anything. It was just a suggestion that not many people consider these days. Audio isn't a cost of living expense, or a sudden emergency that needs to be budgeted. If someone can come up with $500 today, they can come up with another, and another, if it isn't just somehow burning a hole in their pocket.
I'm an example. When I showed up here on AH, I had bought a used set of speakers for $75 while I saved and shopped for a system, and learned what was available, options wise. In the time I discussed it here over a period of a couple months, I was able to save the amount needed (was around $1k) for a killer DIY speaker kit that was suggested to me. I ended up with a set of speakers that performs more in the $4k range for that effort.
Best part about it? I ended up with a new, higher performing system than I would have afforded otherwise just by waiting 2 months, and didn't owe a nickel on it when it was all done. I ended up with a "system for life" that I could afford by just kicking the lending institution to the curb.
Go ahead. Suggest him his "lifetime" system on a shoe string. I bet mine kicks it's ass across the board, for not much more $. Ended up adding subs, amps and building 9 pairs of speakers, 4 amplifiers since, none of which happened overnight.
