Caig pro gold on your standard stuff will not really make a signal brighter, but more energy can be heard, use this on all interconnects, electrical connections, and speaker connections.. All NON-permanent connections that you sometimes need to remove or move around, or unplug, use CAIG in the Nail polish applicator with a nice swipe on coating..
However Quicksilver is only good for one thing I have found, I hate it on all the above standard disconnect connections mentioned.. Any non-oxidizing Gold coated RCA or speaker etc.. Leave them alone or use pro gold..
More Permanent Internal Spade tin type connections like on Speaker drivers are pretty cheap and oxidize in most cases, and I have pulled drivers from speakers in the past, cleaned them up and treated with a nice coat of quicksilver really making them come back to life and give very good connection keeping the oxidation on these types of deals to ZERO.. With very good strong sonic results.. At first it might be a little forward sounding if you do all your drivers, but it will settle it seems at a point and be great power, and you never normally touch these connections again..
Quicksilver is a mess on anything else that you normally handle and I agree sonic results are not really positive unless you really had a bad connection there in the first place, plus this stuff can short out things especially Standard RCA connections. I can agree with above however on TUBE treatments, they are pretty permanent connections in the socket once you put them in unless you are always tube rolling, and it would seem and I have tried in the past tube treating and it works well.. But again most Tube pins are very cheap greyed type not very protected from oxidizing, the nice thing about quicksilver is that it will Stick and stay coated without issue of ever loosing signal unless you are unplugging it all the time, and it does get everywhere and look crappy as well. Oh but Quicksilver does not loosen and thats exactly the first reason I came up with putting it on the Most critical overlooked Connection in the speaker, The Driver spades!!
I can still recommend the Caig in most cases even for the tube pins with great results as well.. Unless you like dealing with the silver mess and Re-freezing the silver every time you use it and thawing it out again.
