Late news. Is it possible the new grounding product for shunyata may improve the equitech 2q by filtering the ground? I also just read fascinating information on Nyquist noise and how Einstein once again had involvement. wow

@ptss Einstein theorized that such noise existed but assumed it was not measurable. Johnson showed that it was and Nyquist explained why. So both names are associated with noise from resistors. Do you know which ground connection is being filtered in this case? If we are talking about the 3rd wire of an AC outlet (the ground connection) I find myself skeptical. This is because a properly designed bit of audio gear should put no noise into the safety ground- although that word 'should' is there telling you this does not happen all the time! Other things unrelated to audio might put noise in that ground. But you might want to keep in mind that putting any kind of impedance in series with the safety ground could lead to Bad Things- like a shock hazard, as the difference in potential between the equipment and the basement floor could be enough to create a shock hazard. Its on this account that I don't do anything that might mess with the purpose of the safety ground. |
I hate to be the guy who farted in the elevator, but... ...with regard to residential 120VAc service in the U.S, "balanced power" doesn't exist for all practical purposes. Theoretically you could create true "balanced" 120VAc power starting with a clean 240V service and adding two massive transformers. Expensive and probably noisy. The companies that are advertising "balanced power" solutions are really selling power isolation. That's good (depending on your perspective) but it's a different thing altogether. |
That’s simply mistaken. There are plenty of truly balanced isolation transformers offered for audio, going all the way back to the old API units. Here's the Equi-Tech schematic:
