Grounding cable question

Dustin recommended connecting my Cascade and s500 to each other with a grounding cable via the grounding posts. The s500 has 2 grounding posts does it matter which one I connect it to? Additionally I have a long (2m) nordost 10gauge qkore grounding cable. The terminations won’t connect to posts, I do not mind cutting them off and expose the wires on both ends to the grounding posts, would this be fine?

Either ground on the amp is the same. We included two because I like to use shielded speaker cables sometimes, two posts allows the shields to be connected neatly. I hate to see you ruin your grounding cable, before you commit to surgery maybe try some wire from a hardware store. The ground wire is not always the optimal configuration for every system so it is wise to try it first with some cheap wire.

Having the Reference PowerBase and S202 both plugged into the same Gryphon PowerZone 3.10, I connected their ground lugs using two Russ Andrews ground wires: one from PowerBase to PZ and the other from S202 to PZ. All 3 devices have a ground lug. A sort of “star” configuration, so to speak.

Contrary to what recommended by MSB manual, I didn’t lift the jumper between “Amp Ground” and “Chassis Ground” and connected the spade’s ground wire to the “Chassis Ground” lug. Why? Because my connected ground wire goes to the PZ and not to the amp.

And similarly the other ground wire goes from the S202 ground lug to the same Gryphon PZ ground lug.

Can you explain the difference between the two lugs on the PowerBase and if my set up with the jumper is wrong in your opinion? Thanks in advance.

There os no wrong, only options. The “tied” jumper grounds the internal shield to the case and AC safety ground (on the power cord) the “lifted ground disconnects the internal shield and allows you to connect it “somewhere else”, for example the amplifiers ground. I use a “leakage current clamp meter” like the ampprobe ALC-110 (extremely sensitive) around one of the analog cables going from DAC to Amp to determine the optimal grounding. You just try to minimize the current on the analog cables by whatever configuration of ground you can try.

Thank you for including 2 sets! I use one on each of the M205’s for common ground (ie to the Cascade) and the other for ground for the REL high signal.

By giving me 2 posts I reduce the clutter and complexity and have room for the AQ Dragon ground wires
