Power cord heiarchy


Which power cord is the most important, or alternatively which PC position makes the greatest difference in your system? Here are your choices:

1. wall outlet to plc
2. plc to source (CDP/dac)
3. plc to preamp
4. plc to power amp

Agree with Elizabeth on 1. Then say 2., 3. And 4. A tie after that. I am a big believer in good power cords in proximity to gear and interconnects. I would upgrade my outlets before cords, YMMV.
You have to try it out. There is no rule that I have found to be consistent, not to mention that the science around all this is nebulous at best.

The front end will help the entire system and often this is where you have most of the interconnects, phono stages etc. Good isolation counts here but that should be easy to assess as most of these sort of problems are very audible.

I have found power cords making a difference even before power regenerators (shouldnt they make zero difference since power is completely regenerated?!)

But the most important thing about power is that your own home electrical system, noise etc is unique. And your equipment may be excellent or not but its interaction with these issues is component-specific and it relates to how good, isolated etc the power supply is. It also will depend on the design itself, ie are you using tube SETs or some ss baanced system or what.

Having said all that, I find that the biggest difference I can discern in my own system is when I power the phono stage, especially my Goldmund ph3, with different power cords. The effect is less with the wavac phono, maybe because of its extreme design on the power supply (3 boxes.)

Enjoy, this is worth trying out, it makes quite a difference.

Best,

I would have thought that the design of any highend amp with their sophisticated power supplies would not be in need of a power cord upgrade.You would think that an amp going for thousands would already have an upgraded cord, or if it needed one would not the designer after listening to it included into the amps price. I mean what are we talking about penny copper no more then 6' with upgraded hospital grade connectors at both ends. I am sure if needed it would have been part of the DESIGN and included in the whole package.

The Power Line Conditioner should not be a given. One must try out both ways, with and without plc. There is no guarantee that the plc will bring an absolute improvement. Then, any power cord from the wall is most important as a general rule.

HOWEVER, what one's ears considers to be the best sound may vary widely. Individual preference will vary concerning placement/sound of PCs. I have had instances when the sound of the system using a "lesser" power cord upstream was just as enchanting, though dramatically different sounding, as putting the "more capable" pc upstream.

There are meaningful differences in sound especially between copper and silver OFC power cords. Though the silver is typically much more expensive, it is not guaranteed that it's placement ahead of other power cords in the system will bring the most satisfactory results. This does not mean that I think the silver PCs are not worthy. The bonus with a mix of silver/copper PCs is the ability to tune the rig to a higher degree than with all one type.

Schipo, just TRY it! :)
