Amplifier heat depending on power cable?

Hello,

I have an ML No 27 and I've noticed that when using one of my power cables it heats up MUCH more than when using another cable I have.

Both cables are manufactured by small European companies, probably little known in the US (Hifi Cable & Cie from France, Actinote from Belgium)

Does this make sense?

BTW, the sound is better with the less heating up cable.

Thanks.

You mean your power cable heats up or the amp heats up more using one of the power cable?

It's the amp that's heating up, not the cable.
Thanks.

The link below may help. It may help to think of the power cord as an extension of your house wiring.

I've noticed that my older Burson integrated, with its two 500 watt toroids never got 'hot' no matter how long I left it on. And that was with a run of the mill (but better than stock) power cord from GTT Audio.
The newer Burson, with 'only' a 380 watt toroid and a Zu Mission PC gets very warm to kinda hot if left on for more than 4-5 hours. Having no venting and using the entire casing as a heat sink would lead one to conclude that this is why but the older model was designed that way as well.
Tis a puzzlement!
