Jiggly knob on the Fosi ZD3?

[bachatero]

I recently got a Fosi ZD3 DAC because I needed the balanced output. However, the big volume knob on the front feels a little too jiggly for an otherwise great quality device, does anybody else have the same problem? If you do have the same problem then we can rule out this being due to a bad unit.

100% not jiggly, I had 2 units.
Never seen anyone commenting about it, quite the opposite.
It's so firm that I needed a tool to pull it out.
I think you may have a defective unit.

Mine is also exactly as you describe yours.

Mine too. It's because it's not a potentiometer, but a crappy digital encoder. Digital volume corrupts the bit stream anyway, which is why a real preamp is needed. Best to use the ZD3 as a DAC only and put in bypass. I'm using mine only temporarily as a pre until the ZP3 is released. Mannix up above I is referring to the fit of the knob to the shaft, which is tight. But, we are talking about the shaft itself being flimsy? My knob IS on tight, but the shaft is meh.

BTW, I was getting a issue last night that I couldn't find anyone else having. Every 5 to 30 minutes the audio would drop completely for 1 second. Like the audio file was corrupt, but I rewound and it wasn't. I was using USB/ PC as the source. After the 5th time I got mad and looked for a solution, First I was plugged into a unpowered USB hub. I reconnected the USB directly to the computer. I also rebooted the computer. So far 2 hours and no drop out? Fixed I guess?

I was just wondering if it was the shaft or the knob. Wow, the shaft is bad...
I had to check multiple times the shaft on the 1st unit, I had to use really a lot of force to pull out the knob and I was worried.
But it never wiggled even a bit.

Hopefully yes. Always avoid Hubs.
On AMD processors, if it's a desktop PC, try to use a a USB port connected to the CPU and not the MB Chipset.
It doesn't look well for the quality of your host USB.
If you don't have already something similar, try if a Topping HS-02 helps.

I have my Fosi ZD3 plugged directly to a type C USB port on my computer. I never had any dropouts, even in DSD 256
