It depends on which configuration the SR8 is in. I previously said that SR8 sounded most like Aurora in the 1-0 config, but I think it's more accurate to say 0-0 sounds most similar to Aurora. In that config, SR8 has a bit more treble emphasis than Aurora while still being pretty laid back, and with a bit less warmth and similar mid-bass quantity. They have similar note weight and neither is thick nor thin(Aurora is a little thicker). The Aurora has awesome DD bass that probably some people will prefer, if not for the inherent characteristics of a DD, then maybe for the increased subbass emphasis and rumble. Bass just might be Aurora's best feature. SR8 sounds more spacious to me but Aurora is no slouch. In the 1-1 config it's a completely different story since SR8 becomes like a party on your head. In the 0-1 config SR8 is a lot brighter, without being too much(for me). SR8 has more of a wow factor while Aurora really grew on me, almost to the point where I feel seduced by it haha. Both are very very musical and punch way above their weight imo.
