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 guess I’m lucky. I’ve never had tubes sound bad right out of box. Having said that, some tubes get better in a few hour.  It’s not hearing bias or my ears adjusting.  I usually by an extra set when buying tubes,( just in case ) and have A/B them after a few hours and they do sound better.
 

All the best.
