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?

My BelCanto Ref 1000 is rated at 7 amps, so at least for mine, all that is needed is a 10 amp cord. You ask about gauge, but you need to be concerned about amps really. I installed a big heavy one rated for 15 amps, but can't say it really makes a difference over the stock cord.

Swanny the amp has a 15 amp IEC and therefore requires a 15 amp power cord. The manufacturer does not list amps in its specifications.

I might be wrong but it seems like evtime I put in thicker cords such 7 to 10awg in my class-D JRDG, it (seems to) gain more dynamic & aggresiveness but less musicality and soul than the 12 & 14awg aftermarket ones. The stock one is ok, but, to me, it sounds kinda close-up, flat, and boring.
I'm curious how a 600wpc class-D sound. What brand is that? If I want that much power, I'd probably won't want a class-D one ... unless I get to hear one first.

Nasaman, that's good feedback. That is curious. The amp I have is the Cary A306.

It class D there are other problems likie it is calls D and a power cord could help but a Solid Class A or AB would yeild better result from a bigger cord. I do not wish to offend anyone. I already had my experimint time with a Class D amps and I have moved back to Big American Class A AB amps.
