Power cord length

The cable manufacturers I've spoken with generally recommend using a short a cable as possible for cables except for power cables, where a minimum of 2 meters is recommended. I will be conducting some blind tests with some friends next weekend comparing 1 meter, 2 meter, and 5 meter power cables. I'm not convinced we'll hear any differences, but it should be a fun test!

My dealer recommended 2 meter for more “conditioning”. I had never looked at it that way. I have two AudioQuest Hurricanes, one one meter and one two meter. So I did a comparison with my stereo amp. I use them both when running the mono blocks. I can’t tell the difference. But audio is all about small additive improvements. So, one should definitely use the same length. 
 

The two meter definitely sounds better. While they are clearly the same power cord the 2 meter is a bit quieter. Definitely worth the money.

"Dealer stated "2m works the best for it to really filter". Also, both cords must be same length for "time alignment"; when using monoblocks "different length wires will sound slightly different"

Oh brother... if that's the case, then have ALL the  PC's the same length-that way everything is "synchronized" to get AC at the same time.

Sounds like nonsense techno babble to take advantage of non techie consumers.

A.N. at it's finest. 

Selling 2M cords makes them more money than 1 meter cords.  I would reterminate them myself to the length I want. 

Power cords should always be as short as possible and avoid loops.

Yeah, I ain't falling for the 2m thing, either. And I do believe that PCs can make a difference.
