So I was thinking of buying Power amp for my speakers, here 2 Aiyima A07 Max costs the same as A Fosi Audio ZA3, so which one would be better?, I would use the Aiyima A07 max as mono blocks. My power needs are 130w (per speaker/Channel) Peak at 6 ohm
 
Since you need at least 130w per speaker, only two Aiyima A07 Max amps could work here because each one can handle up to 166w @ 4 ohms. The one Fosi Audio ZA3 wouldn't be enough for both channels since it can only output 140w combined @ 4 ohms. Hope this helps! :)

Za3 does 140@4 ohm on 2 channels not combined
 
140W per channel would mean 280W combined, but its 48V 5A power supply is only rated for 48V * 5A = 240W, so 280W is impossible unless you want to overload the power supply
 
Here are the measurements @amirm got:
