    Nelson Pass on Power

    Excellent article in Stereophile on power and power conditioning. Interestingly, he does NOT say that power conditioning doesn't add value.

    Re: Nelson Pass on Power

    Good article, though it stops short of grounding at the very end, thanks for posting!

    I am just about to crack open 8 hours of license required code update education. I also invested about $450 in my company for a ground rod driving electric hammer. As soon as I'm on my feet again, I am re-grounding my entire structure.

    I got from the summary that a good amp deals with noise but the less noise coming into the power supply the better. Absolutely, my experience you have to try first because some products do limit, or choke, the current needed to the amp. Many power product manufacturers have gotten wise and offer zero current limiting outlets.

    I did read an article way back on power regeneration which explains the regenerator is an amp itself and to do the job correctly it would be huge and costly. So I decided I wouldn't pursue that avenue.

    On the other hand, some conditioners (e.g., AQ Niagra 5000/7000) can supply additional peak instantaneous current (AQ claims over 90 amps) during short transients, which, I can attest, will improve rather than detract from dynamics. These units are not regenerators.

    Unfortunately the article is poorly written by Jim Austin who doesn't know much about AC power or circuit design.
    Only small tokens of Nelson Pass.

    I'm glad to hear more validation designers are thinking about dirty power. I was suspect about it when MEP said as such to me. Seems he was right.

    Re: Nelson Pass on Power

    And just what does a ground rod system have to do with day-to-day AC power quality?
