Power cord replacement suggestions

I recently found great improvements in my system with the low end Silnote Posideon and Shunyata Venom 3 PC.  Both are around $100 and offer a 30-day trial period.  The Silver Ghost PC was also auditioned, but offered far less improvement in SC that the other two.  Start modestly and then move up the food chain, that is my best advice.  

@nutty, I tried on my previous DK Design VS1 MKII and my current amp, Audio Analogue Maestro Settanta (70). The Blue Heaven did have any effect on either of the integrateds

Manufacturers do not advise to change power cords.  They already had thought about it while designing, listening, showing, and selling the product.  Rest assure, they would not compromise their product over a stupid power cord.  If they could make it sound better with a special power cord, they would.

Why don't they still hardwire? They know we are going to throw away the power cords that come with their products, and add ours, so why would they jack up their cost.

A few manufactures do sell cords with their products. Shindo and Merrill Audio come to mind.

If you study the pricing of certain cords you can buy the best cords to see what they have to offer and resell at a gain. The best I have heard were Elrod, Ch Acoustic, and High Fidelity. l think Lak has heard these cords and likes the ones he recommended better. Very good recommendation.

 Hope the OP lets us know what he thinks, even if he can't hear anything different. The lucky ones don't.

@chrisr  Some manufacturers DO recommend aftermarket power cords.  I received such a recommendation within the last couple of weeks from a well known audio manufacturer. Your statement is a bit too general.
