Perhaps take a listen to DeVore 0/93's. You could do either the LM 211IA which use EL34's, or their KT88 amp. That model # escapes me. Either of these amps with the 0/93's will have you south of 10K. These are tube integrateds, and are IMHO, good bang for the buck. I am a happy owner of 0/96's, and a 211IA, but use them in different systems. DeVore/LM have been paired at quite a few recent shows, so I suspect a listening opportunity may be pretty easy. If you choose a speaker this efficient, you will have a wide range of tube amps to choose from.
