Yes, you can invest on HIFI and make some substantial money. My strategy...buy the pieces that you will keep and appreciate the longest...therefore, pieces that are not a FAD......listen to it to your satisfaction and refrain from ever buying the same type of gear again. You will make big bucks...that means, you will not spend money investing in more gear, that will be gathering dust and increasing your debts or your capital equity. This is the ONLY WAY to make money, unless you become a dealer and buy things on the cheap for your own listening and then, sell them used, still getting the price above what you have paid for the piece, wholesale.
