Power cord supplied with Luxman L-509X Integrated Amp

The Luxman will benefit from a high quality power cord. However, my experience is with power cords which are terminated in US plugs. I guess you are not in the US since the power cord as shown in the photo of your System page is a 2 prong instead of 3 prong. Since I do not have experience with 2 prong cords, I’m not sure if sound quality will be improved with a higher quality cord.

If I’m not mistaken, the connection of 2 prong cords is not exactly a tight fit and rather loose in comparison to 3 prong cords?

It is unfortunate that the forum does not provide the facility or feature to post pictures or links to videos. Otherwise it will be useful and a whole lot of fun.

Heres a chart for ID...

If your wall outlet accepts a 3 prong cord (2 flat/1 round) then a typical (here in the USA on newer gear, anyway) C14 cord will work.

The ground will not be connected @ the amp end as there is no 3rd/round prong.

The stock cord looks like a C18.

You have a pretty standard 2 prong cord. That means the amp is internally grounded and a ground wire is not needed. Nothing wrong with that.
