Power cords different lengths.

I don't even think most of my gear has the same length cords!!

Yes, it's fine, so long as the cords are adequately sized to begin with. 

Power cords act like power conditioners. The greater the length, the more conditioning. I acquired two Audio Quest Hurricanes; one 1 meter and one 2 meter. It was really clear that they both improved the sound, the two meter notably more than the one meter. At the time I had both an Audio Research Reference 160s and two Reference 160m monoblocks, so I was able to experiment.

The audiophile rule of thumb is that all power cords should be two meters… regardless of the distance to the outlet.

So if you would like the maximum benefit from the cords they should be two meters in length. However, I ran the Audio Research Reference 160s monoblocks, one with a one meter and one with a two meter power cord for over a year. There was no problem, the monoblocks sounded better than the stereo amp. But, both being the same length sounds better, but you must decide. Small difference, yes… but given the equipment / systems we are discussing the term small is often combined with notable improvement. If you have a +100K in your system, cutting corners on the details can add up and makes no sense.

@ghdprentice + 1. Ty ghdprentice. That’s exactly the answer I needed to hear. I will be going with the 2 m for the amps.
