Power cord supplied with Luxman L-509X Integrated Amp

I've never had an expensive piece of hifi that DIDN'T come with a cheap looking generic power cord.  Same goes for interconnects.  BYOC (Bring Your Own Cable) is expected.

Oh boy… Audio Science Review militia has embarked 

What is physically happening in the cable that produces a better sound out of the system?

And can it all be measured?

Assuming this was an original US piece, then 2 prongs is all you need, and you'll run into less ground loop / noise problems.

To use 2 prongs the equipment must be double shielded, so that an internal fault won't route the AC's 120V to the chasis.

I still use a shielded power cord however.  This covers the AC wires in a shield that is grounded at the outlet and has no connection at the Luxman for noise reduction.

Most 3 prong cords are not shielded and cheap shielded cords are available on Amazon.
