New power cord needed for speaker with powered subwoofer?

now that this discussion has cleared up the issue for you...just borrow a few cords, or buy some with return privileges and listen...some of my gear came with real good cords, others with junk, as if they knew no one would use the supplied cord...

Clearthink,

Do you believe peoples’ observatIons are ilusory?

Just asking.

Observations are biased inculding mine, yours, everyones.  Trying to filter out those biases to make a decision is the hard part. 

jbrrp1,

I’m an engineer, and I used to believe on principle that power cords could not make a difference (assuming adequate current capability). But actual listening trials converted me from a skeptic on "theory" into a believer in practice.

Sighted tests, I presume? Being an engineer (or scientist, or having experience in any field) doesn’t make anyone immune to sighted bias effects. That’s why blind testing protocols arose in the first place

That sounds like a great idea. I’d just add that if rvpiano really wants to know if the sound is changing, vs his imagining it, he could just have a friend help him do a little blind test shoot out, his pal switching the "audiophile" cables with the supplied cables, without rvpiano knowing which is which. I mean..he is asking if they would make a difference. If he really cares to know, those steps would help him find out.

It could be a very informative outcome for rvpiano :)

used power cords hold their value a long time, and some are quite inexpensive to begin with,  so really no risk here...
