One comment on that video got it right: what you hear with a tube amp is the output transformers. Okay, technically you hear everything, the whole package. But it gets the point across that there's much more than tubes to a tube amp.
If you're really into 300B then I would talk to Eric about which speaker will be better. Steve Guttenberg is neither here nor there. Literally. Not sure what planet he is on. Electrons certainly will work fine with the amp you have now, and longer term probably more flexible in terms of sounding great with a range of amps. Electrons and a Raven Nighthawk with some good wire between them will be impressive. When you hear Electrons you will know why owner's rave about Tekton so much, and when you hear a Raven you will know why the guy said its the transformers not the tubes. No grain there just massive detail and plenty of power.
