Stage is very similar when using the same pads. Alara are a bit darker at the moment, with less higher treble and more bass quantity/bloom, but again they are quite new, not enough run time shall that matter. The Alara sound a bit softer and the Quads more focused on transient attacks.They certainly look similar with regards to many parts including the driver assembly and what is visible of the driver itself. They do not sound the same, at least the 2 samples I have. The Quads are also a bit less efficient in reality (have to increase the volume to get the same sound level).
