POowerCord for For the McIntosh MA6900


I own a McIntosh MA 6900 Integrated Amp.  I'm thinking of replacing the stock power cord with an upgrade.  I notice that power cords are described as either 15 Amp or 20 amp.   Which rating applies to the 6900?  Thanks

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.
