BLE has a PC for $20.95 + $8 shipping. Why pay more? 

Jump on A PURIST cord ASAP!!

Your gonna find that Mac will like silver clad with teflon and good copper ends.  A # 10 is good. COOK the crap out of it.. or plug it into the refer circuit for a couple of weeks.

I don't care who makes it.. A 4 wire weave, 3 copper/silver clad and one pure copper for noise and a second ground. You can try silver ends, but I quit using them. COPPER ends for a Mac, Just works. Gold is ok, copper is better.

I use an older Shunyata Copperhead power cable with my McIntosh MA6600 Integrated.  

I made a 4 strand copper 9-gauge cord.Very chee for my 6900 works great macs seem to like big copper everywhere .

Just make sure it’s a heavy gauge cable for high current and quality plugs. Doubt a $30 cord is going to smoke the stock one, but good luck. If you don’t have dedicated circuits you will hear a difference but it will be subtle. Dedicated circuits will be more noticeable and will make the change of power cords more rewarding; at least that’s my experience. Tried a lot of brands and I recommend Kimber and WyWires.

Thanks but I wound up with a Cullen Power Cord, 10 gauge running from a Shunyata power conditioner.  This was a new house I moved into.  When replacing outlets with Furutechs my electrician told me, to my pleasant surprise,  I had two 20-Amp circuits where the  former owner's stereo used to be.
