Indeed. Bill Waslo's 'slides' (http://www.libinst.com/Detecting%20Differences%20(slides).pdf) actually point out that a timing/phase error as small as 93 ns turns a perfect null into a 55 dB one at 1 kHz, and a 0.03 dB level error makes for a 50 dB null instead of a perfect one. This is why programs such as audio diffmaker do is apply crosscorrelation to time align the signals, as well as gain equalisation. "To try to judge the real from the false will always be hard.
