Power Cord for Power Conditioner


I'm trying to figure out if it is absolutely necessary to use a company's power cord with their power conditioners. No brand in particular.Any help would be appreciated.
thanks in advance,

Cable nay-sayers feel tremendous need to share their disbelieves posting even on cable forum (posting against cables on cable forum reminds me this deaf guy who answered add for music teacher just to tell them they should not count on him).

Don't be so defensive cable nay-sayers. There is nothing wrong if you cannot hear the difference. Yes, some people can hear better but it should not upset you any more than wearing glasses or being shorter.

Agree. Often amps with the best specifications sound the worse. Deniers demand proof (scientific or blind test) but what they fail to understand is that it doesn't matter. If it is sounding better why to question it. Maybe it sounds better because of faith in cables (placebo effect) but final result is what counts. On the other hand cable deniers might hear no difference because of just the opposite - negative placebo effect but I seriously doubt that they even tried being so busy teaching others what they should or shouldn't hear.

- but people are happy.

I didn't realize how much our senses depend on our thoughts until I learned that one cannot tickle himself just because he knows who is doing that.
Hearing better because of strong belief in cables is very similar.
Isn't it a little silly to post messages against cables on CABLE FORUM?

I don't care much for Vinyl but I don't post messages against it on ANALOG FORUM. That would be arrogant and rude.

I also don't believe in CD tweaks but I don't post against it on DIGITAL FORUM. That would be arrogant and rude as well.

etc.
Well, lets look Rwwear - original poster asked if different power cable can be used and while he was offered by Elizabeth viable alternative of very good and inexpensive Pangea you had to jump in to express your disbelief, as you always do, even if it did not answer original question.

More, you jump on any possible occasion to make silly jokes instead of answering questions. For instance, when poster asked why longer power cord seems to work better for him you answered:

"I held an 8' and 5' power cord up to my ear and I thought they both sounded the same. I guess I'm not an audiophile."

Very mature!
Grant - Let me add that these narrow spikes have width (conduction angle) and therefore peak amplitude dependent on impedance of power transformer and ESR of capacitors (Schaffer's diagrams). Often with huge banks of capacitors in parallel (very low ESR) and big transformers peaks can be really high. It causes big voltage drops in power cords but also heats-up transformers since rms value of power (related to heat) is much higher than average value hence heating windings, while high frequency content heats-up the core. This high frequency content of the very high current spikes is also radiated by the cord. Linear power supply is in reality a switching power supply operating at 120Hz where "ON" time is proportional to load.

As for telling others what they should or shouldn't hear I'm guilty of it as well. I expressed opinion that Benchmark DAC1 is insensitive to transports and digital cables knowing that it has huge jitter suppression (2Hz jitter bandwidth) in order of >100dB at the frequencies of interest (kHz) on the top of very low amplitude of the sidebands (-60dB) created by the jitter. Many people confirmed it but also many found difference in their systems. I don't know why and cannot explain it, but it was wrong for me to say they imagined it. Perhaps something else changed - like electrical noise (FCC requires transmitters to cut power around 6PM), warming of the gear (often ferrofluid in the tweeters), ground loops or just simply I'm wrong and Benchmark is not that perfect. Now I only say that I cannot hear any difference IN MY SYSTEM.
Paulsax - not only that science to measure does not exist but also that current science cannot be trusted. Amplifier, for instance, that has the best specifications most likely will sound the worst.
