So I gather that these newer PX panel are more efficient than prior offerings. So how much of a difference are we talking here? 1, 2, 12db? And what has improved to produce these improvements since the basic physics has remained the same?
The Atma-Sphere’s I believe are a OTL design. Has anyone managed to incorporate a direct drive OTL tube amp bypassing the interfaces? I would imagine the efficiency losses are quite high just due to the interface coupling.
