Power Cord for Accuphase Amplifier


I have a new Accuphase P-4600 amplifier and am looking for a power cord to replace the stock. So far I’ve tried the Cullen Crossfire and the IceAge OFC Frankencable. While both cables have worked well on my source components they have not performed better than the stock on the amplifier. So to those who have Accuphase amplifiers what power cable has worked for you?
 

As I mentioned in other threads Accuphase strongly recommends that you use only the stock cord and so far that has been the best. The. other two have resulted in a darker sound with less soundscape openness. 
 

I’ve been trying to stay under $500 for the cord but would be willing to go a little higher if it improves the amps performance.

@audphile1 "I use high quality power cords” 

understand! the problem with “high quality cords” is a different understanding of key performance and reliability metrics. for example extreme high contact pressure and the same time small effective contact area plug will cut through noble tin (few um) plating layer, thus exposing contact base metal for oxidation. reputable interconnect manufacturer checks contact integrity after series of plug/unplug iterations (x100 times), which helps valued gear to work longer time at the same performance level. “scratched” IEC plug can cause short time phenomena of “hearable” PC replacement SQ improvement, and which is unique to each case. 

ideally IEC receptacle should be replaced together with PC using the same brand/design/series plug, latest rhodium plated contacts are very good to consider, specially for aged gear!

Power cords definitely make a difference in sound. Sometimes better, sometimes worse and that’s why it’s best to buy from a dealer who accepts returns or trial basis. As others have suggested, wait until the unit has 300 hours and then experiment. I experimented with power cords without expectations and was shocked at the difference in sound. Kimber Kables sound different than Audioquest and they sound different than JPS Labs, and on and on.  Paul McGowan of PS Audio said in his YT videos that their power cord is to fill a need and they expect the buyer to get a higher quality.  Never read an advertisement of a electronics company bragging about the quality of their included power cord.  Never.
