I don't know where you are getting any of this. I have tons of DACs that work just fine and dandy with USB as their only source of power. Most have only one USB jack so you can't power them externally even if you wanted to (without building special cables, etc. which I don't do).Yes roughly 100 other DACs didn't have this issue. But it doesn't mean this one is problematic because of the issue --- This one is not powered by AC by design, while other 60 DAC is. And another 25, a power supply is provided by manufacturer, or it's a portable amp with battery. For the last 15 usb-powered DACs with no power supply, you sometimes use a $300 linear power supply to test them.
Nonsense. I have a template for testing DACs and I bring them up and connect three cables: USB, and RCA. There is nothing different. I post the exact screenshot of the analyzer which shows every parameter for full scrutiny.You're not testing your DACs under exactly the same condition and reading the same parameters, which makes your performance benchmark meaningless -
Maybe? Where does logic come from? The company itself says it needs more USB power. When I add an external supply that accomplishes that and the problem goes way. Where is the "maybe" in that?Again, I concede there may be an issue with the product
You seem to still be upset that your company's product didn't measure well and now complain to cast doubt on validity of measurements (instead of compelling your company to improve its products). You are simply making thing worse for yourself when you do this in a thread where my measurements have actually pointed out an issue with a product that is confirmed by the company and my results.
