What Are your impressions?

From Walker's instruction sheet: HOW TO APPLY E-SST/SST:
1) Whether you are putting it on audio and video equipment or something else, the same rules apply. It is best to clean the connections with a contact cleaner that leaves no residue. If the contact is corroded, you can lightly sand or scrape it. Then clean it.
2) Apply a very thin (almost transparent) coat of E-SST to the male end of the connector. I’ve been asked which is the male end. For the uninitiated, the male end of a connector is the part that sticks out....think anatomy! Apply to the male end or to the ring connector or to the end of the spark plug that the plug wire goes to. Remember, very thin. More is not better.

REMOVE EXCESS:
If you get too much, use alcohol or contact cleaner to remove it. Take your time and pay close attention. Use E-SST at their own risk. E-SST is very conductive. If you get it across a connection, you can short out your equipment. When applied properly, you will have no problems. In fact, we guarantee you’ll be satisfied with the results or we will refund the purchase price.

Hi Zd542, Have you used the Walker sst silver compound?, where do you get it?, what are your impressions on this product, or anything like it?

The Xtreme AV Quicksilver Gold is a cryo'd silver contact enhancer with gold content, highly recommended!

Silver and after copper are the most conductive element so using beryllium, rhodium or anything else will alter this conductivity, in a good or a bad way. i guess you should stay simple. i made several try of connectors and the most fluid is still classic copper. Silver tend to be harsh, rhodium throw the frequencies up front...
A 2$ Neutrik connector bested a 250$ pair of WBT but of course it will depend on the flaws of the system...
