"We have done direct comparisons with some of the leading brand names in the market. We can’t disclose the technical results on the Internet for obvious legal concerns. However some of the so-called “2ps, even 1ps” “ Low Jitter” claims, we found to be exaggerated. Our listening test confirmed that we couldn’t detect any differences between our clock and those costing five to six times more. If you can detect any differences, please let us know."

"We can’t disclose the technical results on the Internet for obvious legal concerns", haha yeah right, sales concerns maybe.
