There's your problem. You think the other headphones are comparable to the HE-6 because all you've heard is the LAu. I don't see an issue with a headphone needing more power, but amps not being able to provide. Luckily the standards has risen a bit though. There's something seriously wrong with the audio industry these days. Every damn thing has to sound overly polite and tamed - that is so wrong! I guess people prefer to listen to concerts standing in the lobby these days.
