preamp inverts polarity

this whole thread has gone off base and no one has answered my question.

my preamp requires me to reverse cables at the speaker end, by design my speaker cables have designated cables for negative connection and positive cables. the positive and negative cables are of different compositions by manufacturer design.

my question is if I follow the preamp directions I will be defeating the design of the speaker cables, so which is it?

Your question was also answered by the post immediately proceeding the one quoted here. Here is that post again:

Invert connections on both speakers then listen. If it sounds better then before, leave it. If your cables are built differently for negative and positive, try it anyway.

If your preamp has a polarity switch, use that instead.

Some recordings were recorded or mastered with inverted polarity, so the “right” polarity may vary.

You can see that inverting the speaker connections with every LP or CD is going to be a pain. So if you have a lot of recordings that are made with only two microphones, get a preamp with an inversion switch so you don't have to be constantly behind the amps making the switch.

As usual, you’re pretty much wrong. Vacuums don’t exist anywhere in the known universe.

>>>>What a knucklehead. I stated that a vacuum is defined by the number air molecules per unit volume. A perfect vacuum is defined as the absence of any molecules in a given volume. There are degrees of vacuums, that’s why vacuums can be measured and there are units of measurement. Obviously some vacuums are better than others. Why do you often give the impression one exists between your ears?

Trying to win an argument by insulting someone is a sure sign of losing the argument. 

Anyone interested in the subject should read The Wood Effect. Just received my copy and it covers the (polarity) subject more than I ever thought possible... 

How can anyone hear polarity reversal correctly unless the speakers are phase coherent to begin with?   Many speakers have their tweeters and mid/woofers wired in reverse phase.  That happens because of the nature of the crossovers they use.  Only first order, or full range, single driver, speakers will be phase coherent. Never the less,  the listener may prefer one polarity setting on their DAC by the way the correct polarity improves the bass...  but the upper range will be diffuse when that happens unless the speakers are phase coherent
