Power Cables for Class D Amplifiers

Do Class D amplifiers that are very efficient, high power, (ie 600 watts at 8 ohms 1110 watts at 4 ohms) require the heavier lower gauge power cords (10, 9, 8 guage) that we see used on the heavy inefficient high power and high current amps? I ask because the stock power cable that came with my Class D amp was even thinner than the usual stock cord. It's something like a 14 gauge power cable! Is a 10 gauge or lower power cable needed in this ampliifier class as it would be in Class A or AB?

I don't know if this will help you but I have a 2 channel Class D amp made with Hypex UCD-100 modules. I used the following power cords with it. A stock 16 AWG cord that came with my PS3, a stock 14 AWG from another amp I bought, Volex 17604 PC and an Atlona 10AWG power cord with fancy connectors on each end. With each cord I didn't notice any difference sound wise good or bad.

Now all the gear I used with this amp along with the amp falls into the "budget" category so that may be the cause of me hearing no difference in sound.

Good luck with the search.

Here is an update for my amp situation. I was able to acquire Red Dragon M1000 monoblocks and they sound wonderful when paired with Shunyata Venom 3 power cords which are only 14AWG. For me I found no need to get a 10AWG or thicker power cord on my Class D type amps.
