Wilfredt,
I believe its possible for an 845 to deliver all the punch and dynamics you could ask for if it is used in a circuit that is well matched to the speaker. Pentode amplifiers will deliver that same punch and dynamics to a wider range of speakers.
We all have our preferences, but I have heard most major tube types deliver outstanding sound when employed correctly in a well designed amplifier.
