"ePacket delivery from China" = snake oil

Nice photo of a powered on system with it for the LEDs so you know it's working...too bad they forgot to actually install a cpu on it.

This is standard for small parts from China, whether real or counterfeit, useful or useless.

The actual item is a real product using real filters. I doubt it serves any useful purpose, though. It seems to be targeted at the audio crowd, but is not priced appropriately ($$$).

I've worked on computer systems where the "low current" power supplies were 2500A (massive ECL systems) and noise was not a problem on even a prototype design. And if it was, we wouldn't try to solve it in the M-box (memory) if it was affecting the whole system.

When you have such clean filtered power going to your RAM you don't need a CPU

If these had any value you'd hear about them from more than just a sketchy ebay listing.

Do they do a version with valves made out of oxygen-free silicon?

I'm almost tempted to buy all of these just to do a comparison and make a website to show it makes zero difference since sound quality depends on your DAC/amp/speakers. I'm sure someone has already showed that this is snake oil though, so I won't waste my money.
