I found the little sample he used to give out worthless. Power to anyone who "hears" all the claims.
Maybe I needed to "buy" the discs to hear the virtues?
Another shout-out for the Mad Scientist: his Graphene Contact Enhancer is magic sauce. Prior to trying it, I had moved from Caig Deoxit Gold to Acoustic Revive ECI-50 with clear improvements in both cases. Potency of the GCE is in a different league alltogether: Immediacy and transparency resulting are nothing short of astounding. The biggest impact appears to be on anything related to power supply. In particular mains cables (apply to each connector inside the plug as well as outside), fuses and their holders and to a lesser extent RCA connections and speaker cables, whether ended or bare wire show significant benefits. An all around class act again
Yes count me as another vote for Mad Scientist's tube toppers. Bought 6 to "crown" each preamp tubes. The effect isn't what I expected after buying the disks, cupcakes, and sticks. They all made a clarity difference that was transformative. (Even I'm getting tired of saying that) But seriously, the tube toppers calmed everything down. The music seems strangely more relaxed, deliberate, and a previously unrecognized sense of irritating "jitteriness" has evaporated. Made me feel like how vinyl sounds in its creamy consistency but without the other stuff. (Full disclosure I use both CD and Vinyl) You know how vinyl has that indescribable wholeness? Tube toppers gave CD playback that magic cohesiveness. Highly recommended for tube aficionados.
Sorry to resurrect an old thread but I am astonished by what the free black discus nano's did in my system. When I received them as a free gift with my contact enhancer I looked at them and laughed. They sat on my desk for months. They are hard to take serious. One afternoon I thought "what the heck, it only takes a matter of seconds to try". So I placed them on the speaker cables as they exit the amp. Unbelievable improvement. Music was less garbled, less fuzzy, cleaner, more concise without losing musicality. I found it's best to experiment with placement. The best balance for my system was actually on the speaker cables where they connect at the speaker.
I'm looking forward to further experimentation.
