Hi.
Hmmm, You want to buy a handful of parts for the á price of 1k or more. Good luck on that.
The big suppliers don't make a difference between 1 and 10 pieces with small inexpensive items, believe me I've tried. The kind of price drop for "labour intensive" (for lack of a better word with automatic assembly

) would be IME between 1000 and 5000 units.
There is however surplus sellers, try them. I've ran across a few and the only clue I'm willing to give is Asia. The only problem again is that You usually have to buy the whole lot.
The last option is a samples package from a manufacturer, it's free, but You have to have a company of some sort to make the samples request.
This all is obviously assuming that You want quality audio components. As for scrap, those can be had for the price You want them to be, even considerably less.
Regards
Sam
