just my $.02 on all this back-n-forth, I just ordered a vial and will report back in a few weeks.
I've used Caig De-oxit and QuickSilver contanct enhancer in the past with just very modest minor results, when this thread first surfaced, I was startled to see contact enhancement being recommended due to my experience with the mess of QuickSilver and the marginal results.
One of things that changed my thinking on this was just type into google 'wiki Graphene' and read the science behind this material. There's something electrically unique about this stuff imo.
I have a PS Audio Audio outlet power filter with good VH Audio Power cord. Was reviewing my connections and noticed I'd plugged CD player and Preamp into this PS Audio and the amp into another power strip. Since I'm 99% vinyl nowadays, I unplugged the CD player and plugged my Conrad Johnson MF2250 amp into the PS Audio filter and relegated the cd player to the regular power strip. Very suprised what that little change did to improve imaging and noise floor reduction, so I'm optomistic that the contact graphene will convey more of the same.
Rest of the system is VPI Prime with Audio Technica Art-9, Supratek Chenin preamp, Revel Performa M22 bookshelfs. Hopefully this will scratch my upgrade itch, was eyeing the Paradigm Persona B which would set me back 7K so 300 is a bargin.
I'm drinking the kool aid nellies!
