P15 vs P20

This link will more than answer your question if the
P15 can handle your system…

How about a P12 handling 2 Emotiva XPA1s in Class A mode
and if you scroll down further you will see a Plinius amp
in there as well…P12 not breaking a sweat…

Don’t make a mountain out of a mole hill

Have fun looking through this thread.

The P15 will be better than the P12 you just saw…

Best wishes
