AC12 power cable length - do I really need 2m cables?
If I only need a 1 meter power cable to reach the power, do I really need to buy a 2 meter cable to get the maximum benefits from an AC 12 cable?

I want to buy some AC12 power cables.  If I only need a 1 meter power cable to reach the power, do I really need to buy a 2 meter cable to get the benefits from an AC 12 cable?

I read a thread somewhere and the founder of PS Audio commented on power cable length.  What I took away from the article was that anything less than 2 meter power cables isn’t getting the full benefit of the cable.  Is that true?

The issue for me is that a 2 meter AC 12 costs twice as much as a 1 meter AC 12 – times 2 power cables – that’s $1000 more to buy 2 meter cables over 1 meter cables.   I would hate to buy 1 meter cables and then find out that there’s minimal improvement in sound quality because I really needed to get 2 meter cables.  And I’m too worried about counterfeits to risk buying used cables.

Can anyone please clarify or share your experience with cable length?

Thanks,
Danielle

Hi Danielle. My two cents. . . there MAY be a little bit of a stronger benefit from the longer cable. . . but it’s not really in my system quite noticeable. . . I would not fret. . . if you need a 1 meter length, buy a 1 meter length. I have 1 m, 1.5 m and 2 m AC-12s in my system and they all sound . . . wonderful. . . to me.

Welcome, Danielle!

I similarly buy and use whatever length I need for a given component.  I played a bit with length and did not notice a significant difference.  There may be a tradeoff in increased electrical noise/EMF with a longer cable, but I do not know.

Think of the “benefit” of AC-12 in the context of “doing less damage”. A 2m AC-12 isn’t doing “less damage” than a 1m AC-12. So buy the length you need.

I cannot comment on PS Audio’s power cables, as I do not presently have any, but my Dealer told me that Nordost power cables generally are best at a 2m length and so that is what I have bought and used. I did make the ‘mistake’ of buying a shorter cable once for a phono pre-amp and it sounded dreadful. Changed to 2m; all was well…

The one concern I have with shorter AC12’s is that the cables are hard to bend into position and it may be easier to work with a longer cable.  Most of mine are 1.5 meters, partly for that reason.

And welcome to the forum!

Don’t discount using AC-5 either, that is a very nice cable. Bends nicely and fits in places where AC-12 might not go. I think PS Audio make the best power cables, particularly the moulded barrels design. If you look at other cable manufacturers, Shunyata Research, Crystal Cable, Nordost, Audioquest etc etc, they all use assembled fittings with screws, plastic shrink tube, and mostly whimpy prongs.

For my money, AC-5 is the cable of choice, but having said that I think I own more AC-12 than AC-5.
