Free tweak #3 for True Audophiles

Another thing that's even easier than installing a cheater, is to simply check the polarity of all of your plugs that can be reversed. A lot of people don't think to do that (especially ignorant old dinosaurs like Arny Krueger, who don't even believe polarity has any audible effect). I use music to test for correct polarity. Certain music is better for checking proper polarity than just anything. Often, I'll take out my Sheffield Track Record LP (or CD) to test for polarity (or my Chesky Test CD, which has a trumpet track for polarity testing), by hearing how the drum is struck. It will sound right (properly struck) when the plug is correctly inserted, and wrong (inverted) when it isn't. Been there done that, no effect. A freind of mine who was a TAS/Stereophile dogmatist, thought he'd investigate this "tweak" and yes he did use music. I happened to be at his place when he was in the process of trying this out, so I had the opportunity to let him hear the difference between the "proper " polorization and the not give a crap version. So without heim knowing which was which I wouold switch between them and he would listen. No effect that he could determine. There is, however, a possible technical reason for checking the polarity of mains cables: the mains transformer has a certain capacity from core to ground, chassis and encasing. If you reverse the plug (here in Holland that's possible even with earthed plugs), there may be a different current flowing from live to case (very smallish, but still). Because in general, in consumer electronics, grounds are connected via the ground wire or screen of interconnects, these currents will flow through the screens of the interconnects. With sensitive gear, this may well result in a higher S/N ratio. This is easily measurable, and sometimes even audible. One reason more to use real symmetrical XLR connections and cables. -- - Never argue with idiots, they drag you down their level and beat you with experience. - I'm not familiar with Euro electrical standards. In the states it's not unusual to have a small (mv) current on the neutral relative to the ground or earthed connection from a lighting dimmer or touch lamp or motor. If it exceeds a volt or two then it becomes an audible problem. The transformers I have encountered have always had the winding connected between hot and neutral. Core grounded to chassis. If the chassis is grounded to the earth at the AC power source by the power cord or a separate third wire to the power strip, how does reversing hot and neutral improve the situation? This is not to be confused with reversing the polarity of speaker connections, which is a phase issue (_ _ _'s speakers suck) :-) It is tobe so confused, if you invert the polarity of all the speakers. -- Posted via NewsDemon.com - Premium Uncensored Newsgroup Service -------http://www.NewsDemon.com------ Unlimited Access, Anonymous Accounts, Uncensored Broadband Access |
