Tube preamp topologies and music

I am searching for a tube power amplifier. I know very little (nothing) about what the pros and cons of tube topologies as they relate to certain types of music.

as an example, let’s take hard rock/heavy metal. It seems to be the consensus that say 300b single ended amps would be the wrong choice even if you had 100+db efficient speakers. Why is this?

Also, tube compliment. 211? EL84? 300B? I understand that they have power output differences, but what else?

 

I welcome everyone’s input.

A OP - As to your specific question, single ended 300B amps tend not to be very well controlled in the bass - even with efficient speakers.

A 300B valve is only good for a couple of watts before it starts to distort. A say eight to ten watt advertised SE 300B amp will not deliver that wattage at 1%THD.

So they are not a good choice for rock music.

The following link will give you a good overview of technical issues related to SE amps - a "high powered" one in this case.
