Although the weight of the speakers does not necessarily suggest a better sound, 300lbs is a testament to the substantial amount of physical engineering that's gone into the design of the N800 nevermind the amount of background research and technology that's gone into its creation.
As for soundwise whether it sounds better than the Piega or not, I would leave it for others to comment since I've not heard of the Piega.
