RCA Caps


Any body have any comments on whether these are worth using?
I assume they are essentially a shield for unused inputs.

I've been thinking about them for a Steelhead, but then, that's a LOT of unused RCA's, and a lot of sensitivity. I think the money's better spent on tube dampers or audiophile-grade fuses, though.

Thanks for the replies gents, i dont use them at present, but only use 1 input on my Asr, so considered them but maybe ill stop fiddling for a while and buy a cd instead.
