Now, let's take 2 systems, measured at the listening position, same distortion figures, noise, frequency response, impulsion response (no null test though), would it be possible for those systems to sound different to your ears?
 
 

Even the same system heard twice from the "same" listening position can sound different, more than likely because of comb-filtering than anything else. See post #3.

Some times my music sounds rubbish because my mood is rubbish. I also find that late at night is when music sounds the best. Measure that, as it it is nothing to do with the electronics.t
