Hi,
Interesting, I also owned both LS50(2012) and Zensor 1(2011). Despite quarter the price of LS50, I agree with you, Zensor 1 is quite good.
However, for extra money, LS50 improves in many key areas. Bass goes deeper and tonality is much more balance compared to Zensor1.Zensor 1 treble seems hotter and quite fatiguing .
Simply put, everytime we(my wife) hear music through Zensor1, she asked for LS50 because every music thru LS50 is more sweet and lucid. After sometime with LS50 she usually fall asleep on my lap*biggrin*.that tell something right. Worth it*dirol*
