All I can say is that my Super Solid Edge sounded very harsh and toneless to my ears, and those who heard it. Of course the Edge consisted of three pieces of compressed wood (walnut ring and two maple rings into case). Don't know if that made a difference compared to the regular, one piece, Super Solid. With all that said, some of the a Super Solids I've listened to online have sounded great. Perhaps I simply had a lemon. It happens.
