Capped off?


Good morning to the community!  I am using RCA caps (from Cardas – don’t know if that makes a difference) on all my unused ports.  Supposedly, they help eliminate crosstalk between the outputs and inputs.  I’m really not sure if I can tell a difference, but they sure look cool!

Anybody else using these?  If so, I would be interested in your thoughts.  Thanks!

A bit confused...

I made "shorting" plugs years ago for unused RCA inputs on a couple of phono preamplifiers.

I wired a small resistor from the RCA's center post to the RCA's outer band (as I was instructed to do).

Forget the value, but it was small.

There was a marked sonic improvement, though the (2) preamps were inexpensive battery powered stereo units that I ran as dual mono's for stereo (simple way of beefing up the power/battery supply).

I bought a bunch of no name RCA caps and also caps for my unused XLR ins and outs on eBay. At the very least, it keeps the unused inputs and outputs clean. Never heard a difference although my systems are dead quiet to begin with.
