M-Lore Owners

Are any M-Lore owners using a EL-34 tube amp? If so, please share your experience. I'm seriously thinking about moving from the Polk LSI15's to the M-Lores. In my 25+ years of experience, I know price doesn't always equate with quality, but at $650.00 would this be a lateral move, a step up or a step down. What would be the difference in sound?
Gonna play a lot louder, that's for sure. You might want to consider the Pendragons if your budget will allow...
