Simple question, probably stupid

Is it necessary to have sound (music or white noise) playing through the speakers when burning in new tubes? I have bought a matched quad of Shuguang KT88 Z Black Treasure tubes to compare with my current Gold Lion KT88 and Tung-Sol KT120 tubes in a Rogue Stereo 90 amp. Reviews of the Shuguang tubes indicate that they need around 200 hours of burn in to reach their true potential but I am not looking forward to having to listen to 200 hours of crap sound.

I suspect they’ll sound great fresh out of the box…with potential to improve even further from there with time.

Admittedly I’m a bit of a burn-in skeptic anyway. It’s a very convenient way to minimize returns. I won’t mention the brand but was told a firmware update requires 300 hours of burn in.
