Mike, what are those "orphan" cords back there?
don't want to distract Ron's thread vibe right now. but i have zero orphan wires.
the dual coiled cables are the cables from the passive main speaker towers to the upper and lower bass amps on my bass towers.
the thin wire on the right is a grounding wire from my Tripoint Troy Sig to my passive speaker terminal plate. the thicker wire on the left is a grounding from my Entreq Poseidon/Silver Minimus also to the passive speaker terminal plate, and then thicker wire off to the left is another ground wire from the Entreq to the active bass amp mounting plate on my bass tower amps. the two parallel very thick wires are my suspended speaker cables. these grounding things were worked out 6-7 years ago or so. every couple years i remove it all and re-install it to verify it's helping. tweaks cannot be assumed as your system evolves they can hold things back.
at the top of the picture are the two Absolute Fidelity power cords for the bass tower amps, and an idle set of EA Triple Run 20 amp power cords (for the 468's) as i'm auditioning a new version of the EA power cords.
so i guess there are a couple of orphan power cables after all.
if you have further questions about this, out of respect for Ron, maybe find a thread about grounding or Tripoint and ask me there. happy to get into the weeds with it.
