Depending on room size and volume levels you may be ok and at the bare minimum of needed pwr.
A general rule of thumb with Set tube amps for optimal sound is to never exceed 1/3 of their total output saving in reserve the rest for musical transient reproduction for those to be reproduced accurately and not be squashed and smeared.Another sign of of being underpowered is the soundstage will close in and not be as dimensional as it could be.
I have owned many different Set designs over the yrs and found these characteristics with every one of them,just a nature of them,and also the overall distortion will increase tremendously when pushed harder,some may consider this ear pleasing but I find the exact opposite being less truthful to the music in tone and timbre,which if not reproduced accurately to the recording is a no go for me.
Enjoy,
