Hear me now and believe me later ... this is a "solution" in dire need of a "problem" to solve. In other words, a scam - a hoax - snake oil - voodoo - audiophile BS. As is the entire subject of "cable burn-in". Whatever changes might take place in a cable (or in any electronic component other than a loudspeaker) is gonna be so infinitesimally tiny and insignificant as to be one helluva joke! And the joke will be on he who believes fervently that some magical sonic improvement is gonna come forth as a result of whatever "magic" is being employed.

As Mike the Monster Man and Da Worfster have already told you ... you don't need any such device as this - even if it sold for $12 dollars instead of $1200.
