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.

Super Tesla SE PC works wonderful on Rowland 8T amp over 250ch RMS very open great deep stage, great body and weight ,wonderful highs etc.I think its a lot of cable for the money as well.

Ebm, I'd like to hear my system with that cable but the price of ownership is too high.

I used Shunyata Annaconda Helix on my Red Dragon Leviathans.

These gave me the best sound, compared to other PC that were DIY or name brand.

I think the bad rap given to D amps is because those who didn't like the sound used no upgraded PC or did anything to the power.

In my expereience,D amps perhaps are more susceptible to dirty power than most SS and the more forgiving tube amps.

They will let you hear what you are feeding them.
