At $50, you are not going to get anything that is a significant improvement over stock cables. In fact, the sound may actually be worse in some areas, depending on what you get, such as gold-plated plugs or even bare copper plugs. The bare copper plugs are not that bad, but not as good as plated.
I'm very surprised that you would only be spending $50 on a power cable against equipment worth many thousands of dollars, lol.
If you DIY, probably the best you are going to do is to get some Wattgate "Classis" series plugs ($24 for IEC plug and $16 for Male plug). DO NOT BUY the Wattgate EVO plugs!!! They use hex head clamp screws which strip really easily. Then buy some 12awg construction power cord from home depot and terminate using the Wattgate plugs.
