In line with this thread though, I am confused why you need 3m power cords though- most people have the components close to the outlet or power conditioner and have longer interconnects to the amps, or longer speaker cables.
@mclinnguy , to answer this I will say that my life is full of compromises. Up until sometime in late '17 my gear was set up with the stock 3m power cords in my living room, and something occurred that made me feel I would prefer to listen in a basically unused back bedroom. Therefore I hauled all the gear to that bed room and set it up and then scoped out where I thought I should put outlets to accommodate the stock 3m power cords and then I commenced to install outlets and drop in dedicated circuits to them.
Sometime between then and now there were a plethora of dedicated circuit threads here on A'gon and one of them made me decide to go from using three dedicated circuits to using one, and that prompted me do once again break out my ancient power conditioner which may be a glorified strip. Then, last summer, I got interested in upgraded power cords and I started down the road with three very affordable 2m cords which made the reach okay because the amp is positioned where it will reach a pc with a 2m cord and the pre and cdp were already using the glorified strip, so 2m worked okay there (then) also.
Present date: I bought three new upgraded power cords and wasn't really thinking about possible ramifications of their 2m length. My intention was to run the pre and amp directly out of the wall on one duplex and run the CDP out of the wall from another duplex and completely go without the power conditioner/glorified strip. It was at this point that I realized that the location I had put the outlets in when I installed three new circuits worked fine for stock 3m power cords but fell maybe a foot or a bit less short with 2m cords. Hence, for the time being, I am still using the power conditioner/glorified strip for my pre and CDP and the amp is straight out of the wall, and for the time being I am going to run it out of a separate circuit from the pre and CDP.
That's the short version. And I type this next in all seriousness: from reading your posts/questions it does appear that you actually read through the entire back & forth in the thread before you started typing.
