Listening to Phono Preamp Burn in Disc?


I have read a lot of posts regarding using a CD burn in disc (e.g. Granite Audio's) to burn in phono preamps. I get that, but I'm puzzled when people who do this complain about having to listening to the disc, as the sounds are not pleasant and repeat ad nauseam. My question is, why listen? Can't one just leave the amplifier off (assuming non-integrated amp), and still achieve the same burn in results? Also, if the amp needs to be on, couldn't a suitable resistor be used to substitute for speakers?

Thanks,

You can always wire one of your speakers out-of-phase (put red wire on black post and black wire on red post), face speakers toward each other (inches apart), put a thick blanket over them and play the disc.
The source material must be mono in nature.
The out-of-phase signal cancels itself coming out of the speakers so the resulting
volume will be lower than normal.
This is also the procedure to rapidly burn in your new speakers.
