Has anybody tried covering unused rca jacks on their preamp or a/v receiver with Cardas Caps? Another snake oil remedy or sonically worthwhile? Thanks, Ed
i have plastic bits that came with my accuphase dc-330 ($16.5k MSRP) to cover unused single-ended and xlr inputs/outputs. they keep the dust out of the innards. just like the ridiculously-priced cardas caps do (and nothing more). -kelly
