So you're saying it just works on a human level & doesn't actually do what they claim (ie: accelerate the burn in process & do a more thorough job)?I myself don't use burn in cd's, to burn anything in,I do use professional audio bench equipment at different low frequencies to break-in woofer roll-surrounds before auditioning.
What I'm saying is that if your in the same room when a burn in CD is pounding your system into submission, it's also notching out your hearing at that same frequency, and maybe this is why some say there's a huge difference in sound.
