Hypex is working on SMPS designs in this order.

UcD700

All of them are OEM only products which means they have to be bought in quantity. That translates to big investments in product no matter how you slice it.
For me, it is a simple dollars and cents game. I look at how much I'd have to invest, time, and the potential market, upside potential, downside potential, liability risk, legacy cost and I make a business decision. I also look at what my competitors can do. Since Hypex will sell them to anyone with the money, I could invest a significant sum of money and find out I have three competitors selling the same product overnight. The product is pretty green too. I've learned the hard way to let other people cut their teeth on the early production headaches.
The cost of developing the power supply isn't that much. I could build a steel chassis that wouldn't cost much but people wouldn't buy it. For this kind of product people want a fancy high-dollar chassis. The market is people with significant money and they don't want to buy from a guy with a company name of DIYCable. There is significant risk in terms of legacy cost and liability (say your amplifier goes poof and you smoke some guy's $50,000 pair of Wilsons). There is a lot of hand-holding, 30-day trail cost, etc... that goes into selling $5k monoblocks.
In my judgment, I'd be putting a lot of money into something I couldn't sell for a profit or that I can use my money more fruitfully with less risk somewhere else.
I am doing a production run of speakers with Hypex amps though. They cost a lot less than $5K/pr
