Cheap grounding solution
By chance I happened on a good use for disused power cords: Disconnect live and neutral leads at the power plug and connect them all to ground. Take off the IEC connector and terminate all to a single spade connector. On your DAC or preamp connec...

Cheap grounding solution
Alternatively terminate with RCA plug not connecting the centre pin and use spare RCA input on Pre or DAC The UK has a different method of grounding an electrical service in a residential dwelling unit than the USA as I understand from what I hav...

Can an unused cable break in?
Voltage is a differential. It is in other words measured between two things. Across a circuit. Without which (a complete circuit) there is no voltage, no amperage, no capacitance, no nothing. (Try buying a meter that can read voltage, resistance,... 
Can an unused cable break in?
It is considered that some of the long time period it takes for some particular cables to burn in is the 'burn in' of Teflon dielectrics. Some cables might be 100 hrs and some might be 500 hrs. the 500hr burn in ones , when looked at closely...

rvpiano OP1,748 posts06-12-2021 12:17amJea48,There is definitely an on/off push switch on the front panel of the CD t accessible by the remote controlIt could be that I have an older model. @ rvpiano What does the switch control? AC Mains power? ... 
Can an unused cable break in?
Connecting to the AC Mains Supply Connect the socket on the AC Power cable to the AC Power inlet d on the rear panel of the CD t. Now connect the cable to a suitable AC power point.  There is no mains power switch on the CD t. To switch off the ... 
What happened here?
Kind of looks like maybe some type of contact treatment/enhancer was sprayed into the contact body. Maybe the stuff has gone bad, deteriorated . What piece of equipment was the IEC connector used on? Maybe a power amp? Poor contact pressure will c... 
Main vs. sub panel for dedicated lines
MC,I was looking at your system thread and read this: Stewart Marcantoni taught me it all begins at the wall. The System begins with 4 ga wire at the panel. This 4 ga brings 240v power to a step-down transformer located just beneath the system. N...

millercarbon9,434 posts 06-03-2021 11:27pm I would also recommend grounding the ground to ground, and then grounding the Earth to ground. You never can be too sure, so I would ground all the grounds to all the pipes as well. Because, like, they g... 
Main vs. sub panel for dedicated lines
Can each rod individually be connected to ground in the main panel? Sure. Especially for your situation. Both rods ground wires would connect to the service entrance neutral conductor neutral bar..

lowrider574,353 posts    06-03-2021    3:04pm Question: why are two ground rods used?Hi @lowrider57 From one of my above posts: 06-02-2021 8:24am Minimum required number of driven ground rods for the main service panel technically is one, * IF *... 
Main vs. sub panel for dedicated lines
For a sub panel in an out building, separate building, a ground rod (Grounding Electrode) is required. The ground rod is connected to the equipment ground bar in the sub panel creating a grounding electrode system for the separate building.For a s...

lowrider574,352 posts 06-02-2021 10:37am @jea48 @mesch I have a new service panel and a subpanel. When the sub was installed, a second ground rod was added. Two different electricians installed the panels, both said two ground rods were required...
