Do I need 10 gauge power cord if I have 10 gauge from panel?

Cable discussions here tend to come down to beliefs. I believe a cable can improve the SQ. Or, I believe it can’t. But this issue is not about believing. Just listen and hear for yourself. No belief is required. Reshelving fees make us want to know what’s possible. In the end, your ears tell the truth. While at an audio show, a manufacturer swapped out four of their power cords. Frankly, I was a little pissed that I heard differences. I wanted to hear the same SQ from all the cords. Even though the SQ was unmistakeable different, I chose not to spend $1,000 on a power cord not because it wouldn’t help but because i have some ceilings on my spending. You can believe me or not but there’s no reason for belief to enter a cable discussion. As for the science behind it all—it doesn’t matter. You hear it or you dont. Whatever your answer is, you’re right.

@Ditsua:

What is the current rating on that Crown amp?

@pennpencil Exactly!  If you hear a sound quality improvement by upgrading power cables then proceed as your finances allow. You don’t need to hire an EE to tell you what you hear.  

14 awg is never big enough for an amp.   I have seen 10 awg power cords make huge difference in 5 wpc amps. 

The logic of @johnnycamp5 above is exactly why so many people have undersized power cords for their amps.  But I'm ok with that.  I've bought 2 excellent amps used and cheap that I concluded were sold because the owners had undersized power cords on them.
