New power cord needed for speaker with powered subwoofer?

@geek , I guess the OP could ask the dealer or manufacturer if the cable supplied with the speakers are the proper gauge and rated for use with those speakers. Why in the world does anyone  think this company which has been building speakers with powered subs for years would provide power cables that aren't sufficient for proper use and potentialy hazardous? Has there been a lot cases of people getting shocked or their houses catch fire from Golden Ear speakers providing lousy cables? 

Observations are biased inculding mine, yours, everyones.  Trying to filter out those biases to make a decision is the hard part. 

Use the cord that came with the speakers unless they gave you one from a 1970 hoover vacuum cleaner. I agree why in the world does anyone think that the manufacturers of these expensive componets think they  turn into skinflints when it comes to the power cord. If they are that cheap then don't provide any cord and advise customers to buy aftermarket.
