Silver plated female RCA jacks on amp/preamp?

I am always stunned by how cheap Audio Note is with the RCA jacks !

I replaced the jacks and posts on my CJ 350 with WBT, obviously can't do an A/B but thought it made a worthwhile improvement. ASR and some others make better jacks [silver] an option. Most components can use better RCAs. silver or other.

Saw the Audio Note silver-plate jacks--they look very nice for the "low" price. Also, Goertz has solid silver jacks at a higher, but not bad-considering, price.

I like the Cardas silver jacks. I bought a bunch and used them on the EQ box for my Infinity RSIIa speakers.
They are nice. the only thing was i drilled a tiny hole in the flange as the backs ground part had no spot to stick a wire.
Other than that (which was no problem) they were great. i still have a pair laying around...
