I would suggest looking at KT88,EL34,6551 tubed units. These seem to have more punch than the 300b, 2a3, 6l6, and 5881, Units.
I have not had a chance to listen to a good set of 845s but I have heard that they also give a more dynamic sound, however these units seem to be expensive.
I just purchased a cary rocket 88 (kt88) and really enjoy the sound, very black background with a dynamic sound from low listening to medium listening volumes. On this amp I have a tendency to use Triode only, it just sounds better to me.
Perhaps the TAD products might be a good starting point, very inexpensive, good reviews, and EL34s that can be interchanged by changing bias, and he offers in home demos.
