Can anyone tell me the difference between the EF5 amp and the EF1 hybrid tube amp? They both seem to have the same specs... Which one would offer the best bang for my buck? I would be using it with the HD650/HE-500

I'm pretty curious as well.
 
They look identical.  Woah, no they don't.
 
Now I'm REALLY curious.
