What do you mean unrelated, takato might not own or properly auditioned MDR-1R but he owns DT1350, and all other phones are just not worthy.
Exactly my point. I own the DT1350 and the ATH-M50. After the DT1350, the M50's low end sounds hollow and light. It doesn't give body to instruments. The MDR-1R has a steeper rolloff than the M50, which is why I have a say in this.
And yes, I know about the different measuring systems, I was unable to find measurements for all 3 from the same equipment. Sorry. It still gives a relative idea of how the 3 compare.
If you please take a closer look and read the model name as well. It clearly show MDR-Z1000 not MDR-1R.
If you wish to blash the Z1000, it is this way: http://www.head-fi.org/t/510768/mdr-z1000-new-sony-flagship-headphones , I which I might actually join in. :P
If not, get yourself to listen it properly or at least get the right graph to reference...
