XtremeAV Quicksilver Gold alternative?

Is there anything out there that's actually comparable to the QSG? It'll be good if its cheaper too?

Thanks in advance,

So, what positive effect are you guys getting with using the Quick Silver Gold ?
Increased extension.. the signal retains its characteristics for a greater duration appearing to come further out from the speakers while maintaining coherence. Increased clarity and detail all present after a suitable burn in period... in my case it has been two weeks since the first application to most points then a week later additional application to a few other areas.. Does everyone concur?
Ardri , Thanks for your point of view. That is why I bought the stuff.
In all though, using better cables with better connections and keeping them clean improved my system way beyond smearing silver paint on the connectors ever did.
