As long as you didn’t debunk anything yourself, I’m giving you a free pass. I always believe Wikipedia. 😛
Why do some manufacturers reverse preamp polarity in the first place?
My Rogue RP-5 reverses polarity, so I switch the pos / neg at speaker terminals. The manual does not mention this, however, I wrote the company and they the amp does reverse the polarity.
Now my question is...why? I would say 98% of buyers of this amp do not know to reverse the cable connections. I would say most reviewers did not as well. Yes, I realize, polarity reversal is not noticable in most instances. Especially, since many recordings are all over the place when it comes to polarity (at least that is what I've read).
So the question remains...why...why not just have the amp terminals set up so the buyer can just plug in as normal?

Well, Sheffield Labs recordings are actually on the Polarity List as R Reverse Polarity. +1 for George Louis. On a sour note, FIM recordings also appear on the Polarity List as R. A discussion of the Polarity List somewhere in cyberspace prompted this comment. I know everything I've done for FIM has correct polarity. Bruce A.

Are you crazy? I’m just asking for evidence. I assume you’re just running your mouth. The Polarity Pundit has been studying Polarity for many years and has compiled a longish list. What have you done? Nothing. I never said I believe anyone. I’m asking people to support their claims with evidence. I’m not even demanding proof. Follow? |
I get an uncomfortable feeling when the 6 Moons author states, “there’s a 50-50 chance a given recording features Inverted Polarity.” I’m mean how does he know?” I would sincerely like to see someone, anyone, compile a list of say fifty audiophile recordings, LP and CD, with Polarity for each. That doesn’t seem too difficult. So far all we have is George Louis’ Polarity List. Which is great that he compiled that long list, but I have trouble buying into it, primarily because he concludes the percentage of CDs that are in Reverse Polarity is so high. But 50-50 assumes no audio engineers or mastering engineers check for Polarity and I don’t buy it. I’m not saying it’s impossible, just the probability is low. |
It actually doesn’t matter to the average person whether the preamp is Reverse Polarity or Correct Polarity because so many recordings are in Reverse Polarity. So, what’s the difference? Since there are no technical standards for Polarity in the industry one should first establish whether his system is in Correct Polarity in the first place and go from there. |
