Come up with your own products. Sell to your local area and on line. Start searching for products you can put your own trademark on. Offer customers a service level they can’t get elsewhere, can’t get online. Offer upgrade materials. But don’t break peoples’ ass to buy it; make it attractive price-wise. I can think of many products and services.
If Agon had a "like" button, I would "like" what erik_squires and dweller said. Hence, ditto.
how to end up with a small fortune

start with a big fortune, open a hifi shop
I would not actually sell any gear. At least that would not be the major scope of my business. It would be some kind of high-end rental service or pawn shop inspired by sharing economy. I would offer short and longterm rentals and leasing. The client would pay reseller's price of the gear (let’s say 1000$). He would keep the device for a month. Then he gets back to my store with the machine and I give him back 900$. As an audiophile, I’m ready to pay 100$ to test in my system some expensive gear (before I buy it from the manufacturer or from the reseller). I would not care about esthetic aspect of that machine, I would not care how old it is, it may even have some issues. I’m ready to pay even more just to live for a month or so, with some piece of gear which othervise would not be my first choice.
