Silver Circle Audio Vesuvius DC beta. I dont know much about this but I believe it is a power cord with a DC blocker. Has a 20A C19 IEC connector on one end and a standard 15A US plug opn the other. The DC blocker section is connected with Neutrik Powercon connectors. I did find this info on the web: With regard to the new Vesuvius power cord, as I did not audition it, I will just repeat what Silver Circle describes. They found that when DC is present on an AC line in excess of 1 volt, it makes a torroidal hum. They designed a Vesuvius power cord (the Vesuvius dc? - $950 separately) that removes the DC with an inline diode/capacitor circuit. Stanard notes on his website what is even more interesting is that in listening tests, we found that the inclusion of this circuit actually increased dynamic slam and detail in the music. I believe its a result of the theory of unintended consequences, or the travels of the Three Princes of Serendip. This is not what we were looking for, but well take it. Reducing DC and increasing dynamics. In any case, the power connectors are very expensive - over $100 each. So if nothing else it would be a bargain to scrap it and re-use the connectors!
