They are indeed fanatastic speakers - punch WAY above their weight class. It does everything minus the weight and low end/extension of much larger speakers, yet it holds its own. Most of us are using low powered tubes with these. Put a decent and well matching front end on them in a small to medium sized room, and they have the potential to be the last speaker you buy... but if you crave 20Hz bass or have a huge room... you may want to look at the new Lore-based speaker.
