Do powercords make a difference in sound?

Hmmm...I don't think you understand audiophiles, paperw8. A power strip? Are you nuts? And some people do spend $2K for a PC for a $6K amp even if it may seem irrational.

Another reason many manufacturers don't include power cords is that they don't want to irritate many power cord manufacturers while pleasing only one. Also many audiophiles might be irritated that they had to buy a pc that they didn't like.

Mainly, if anything I buy comes with a pc, I just leave it in the shipping box and figure it is worth probably about $3.

I have discussed the subject of designing an amp with a fixed power cord or an iec. several have said that an iec degrades the sound, and a well designed permanently attached will provide superior sign. in fact, conrad johnson wasa using attachable power cords for a long time, and only recently designed their amps and preamps with an iec for marketing reasons, not sonic ones.

at this point in the discussion, i would think that one can sum it all up by the following:

those who believe power cords make a difference are entitled to tehir opinion, while those who don't are entitled to their s' .

there is no way to prove the hypothesis that powercords make a difference, it may or may not be true.

any thing else to say is probably redundant

Computers and portable appliances did help make the detachable universal IEC connectors popular. [http://en.wikipedia.org/wiki/IEC_60320]

i'm not so sure about this explanation. for example, krell apparently decided that there was money to be made in the "upmarket" power cord biz because they introduced the "vector hc power cable". krell says of the vector hc power cord that it is "engineered to the same rigorous standards as krell electronics".

yes audiophiles, if, after spending $40,000 or $50,000 on monoblock amplifiers, you still feel that you haven't spent enough money, krell will now accommodate your wishes by offering you the opportunity to spend another $4,000 on a pair of "upmarket" power cords.
