Burning in question

I bought an NAD M33 for a system in a 2nd home.  I want to run it in before installing and these amps are notorious for needing a lot of time before sounding as designed.  

The speaker terminals on the M33 won’t accept my ribbon cables.  I’m curious if any of you have an opinion or experience to share.  Will an amp burn in just being on, but without a load at the taps, and without playing/streaming a file?

For those who think burn in is hooey, please just kindly move along - nothing to see or hear, here.

Best to all,
