We all have our point of diminishing returns-- I prefer 5 way binding posts for my 0v ref connections between cases. You can use them with banana cables, but a better connection can be achieved with crimped spade lugs on 18ga or larger wire. I'd like to see some enterprising company sell a 2hp panel with a binding post connected to the 6 ground pins on a power connector. That would give a plug 'n play reference module for those unequipped to go rooting around distro boards to find the optimum location.pugix wrote: ↑Fri Aug 21, 2020 3:04 pmSince I get some improvement with a banana lead, how much better would two stacked leads be?Graham Hinton wrote: ↑Fri Aug 21, 2020 2:26 pmI use DINSE-25 connectors and 25mm2 cable for temporary connections between cases (i.e. for live use) and get the resistance down to a milliohm or so. For permanent setups I would make direct connections in the order of ten of microohms. It's all a matter of ratios compared to the 100s of milliohms in cable screens and mains leads. Many people have noticed a loss of background noises that weren't particularly noticeable before, but once gone are not wanted back ("I never realised that Eurorack could be this good"). Do you want a ratio of, say, 3:1 with a banana lead or do you want 1000:1 at little extra cost? Even the banana lead is a 12dB improvement, but you could have 40-60dB.
If nothing else, it would provide a quick and easy answer to questions like this one.
