[Sweetmeat]

I just bought a Hifiman HM801 and it came with 2 amp boards. The spare board is green with 4 transistors and 4 caps, it looks like the picture in the Hifiman manual. Inside is a blue board with 4 big chips and lots of little chips. Does anyone know what the difference between these boards is please?
 
Sorry if this is posted somehwere else but I have been searching for hours and no luck. I found several reviews which list supplied contents but they indicated a 32 GB SD card (which I didn't get) and no mention of an extra amp board (which I did get). Thanks.

(FINAL EDIT): Looks like someone else got two amps with his 801:
