Yeah I do think in terms of musicality grado and MS1i can definitely beat any superlux.Some of my friend do find the superlux HD668B to be boring when comes to music presentation (the ambient and all that).Not to mention that HD668B requires a very good amp/dac to shine very well unlike MS1i and KSC75 which can sound really great even on portable music player.

Sorry about the KSC75 recabled vs. MS1 thingy through.Probably because I like the recabled KSC75 very much I tend to be bias when comes to putting it against any other headphones models that supposed to be very good,at some point even better then the recabled KSC75 itself.

Don't worry about it.Every impression from everyone is useful for those who might interested on buying any of those superlux product.It's more the merrier lol
