Upgrading power cord.. proven upgrade? or crap?

The right way to do lightning and surge protection is with a surge arrestor at your power service panel.  Home Depot has panel-mounted arrestors for ~$60, and external (if you don't have room in the box) for ~$110.  Protects every electronic device in your home, including the stereo. 

Sorry, but you're mistaken. Service panel devices such as those from Leviton and Square D are not designed for lightning protection. For that, they make separate devices that are mounted onto the utility's meter pan, between the pan and the meter. Some electric utilities forbid the use of such devices, which is the case where I live.

That doesn't mean that panel-mounted surge protectors aren't worthwhile, however - but they  just part of the solution to potential electric problems. And at least in my installation, they are not a substitute for a good isolation transformer, or two or three.

Ill give two somewhat contradictory observations. First I agree that technically it doesnt make sense that two meters of good power connections would change the sound. Like high end speaker wires going into pedestrian wires inside the speaker crossiver. But much of audio is like this - it makes a sound difference but its hard to say exactly why. 

Second, my shunyata power cord which was expensive (for me) made zero audible difference with my hegel h200 amp. But I dont have a highly resolving system and I dont doubt it would make other systems sound better. Just not in my case. 

So try it and see. cable company will send you a few to try. 

Hi skoczylas,

You make two points, so I will as well. One, yours is the most balanced, reasonable, and intelligent post I have ever read regarding cables and most certainly involving power cords. Two, well, no need for a two here...

Best to you skoczylas,
Dave

as above, I would be interested in your 91 PC list. Especially, the $18K PC...
