Hello, did any of you have an occasion to compare PSB M4U-1 to Shure SRH940? I have been owner of PSB for two months and adored them, but yesterday I listened to some music on these Shures, and really liked them ta lot too (its BIG dynamic sound) - frankly speaking, when I came back to PSB afterwards, I felt it lacked some bass. The guy working in a headphones shop claimed that in his opinion SRH940 are to die for and much much better than PSB. Just curious - what are your thoughts? How would you compare these two models?
