It seems to be aimed mainly at those who received them before their official availability. ;-)

No, no, no, that's just by coincidence. It's just that not so many Amazon buyers made it to the forum so far.

The one and only criterion for the order remains the owner's good looks!

OK, there might be a second aspect. My WiiM Amp Pro didn't receive its firmware update yet. I believe I look very ugly to my WiiM Amp Pro because the WiiM Amp Ultra is currently getting all the attention. The Amp Pro is jealous.
