To Float or not to Float...
This is exactly how more than half the source equipment that use earth figure eight two pin mains cable get their earth reference, via the interconnect. IF the equipment is Class ll (Double Insulated) Listed that uses a two wire power cord and pl... 
To Float or not to Float...
Correction: If a piece of audio equipment is Class ll rated the power cord will be two wire. In the US and Canada at least the NEMA 5-15P or 5-20P plug will be polarized so it can only plug into the wall receptacle in one direction. That should re...

I have a DeHavilland preamp which has a switch allowing one to "float" the ground. I’ve always used it in the "float" position, however recently, perhaps due to some connectivity issues with my interconnects, there is a small buzz emanating from ... 
Maestro faceplate - does it make a difference?

DC leakage from power amps
@crazyeddy,What are you feeding the two amps with? I assume each amp has its’ own 120V 20 amp dedicated branch circuit. Roughly what is the distance, length, of the wiring from the electrical panel to the wall receptacle outlets? What are you usin... 
connect 2 different wire gauge to pos and neg speaker terminal
Al (almarg), What is the stuff that flows through a light bulb and comes back out again through the other wire? The answer to question #1 is ELECTRIC CHARGE. Charge is a "stuff" that flows through lightbulbs, and it flows around a circuit. Normal... 
Need suggestions please! Electrical noise in my system and it's driving me crazy!
Edit to my post above.When I spoke about cleaning the connection of the electrical service’s #6 copper ground wire at the ground rod I should have mentioned with extreme caution. There could be a lethal difference of potential, voltage, between th...

nutty1,212 posts 09-03-2017 1:29pmI also recently eliminated a hum by disconnecting my CATV from my system. After re-grounding it, removing the ground and trying power conditioners, I could not eliminate it until I unhooked the coax from the sys... 
DC leakage from power amps
@crazyeddy,Not sure if it is relevant to the discussion but what are you using for speaker cables? Brand, type? Approx length? Wire gauge?.
