After i read all the pages, yes took me several days to do it, i have some doublts about some things:
1- After some research, i will buy the HD 660 S...should my laptop with ess sabre capable to play without an amp or dac? The laptop is the MSI GT75 8RG, and have the Hi-res logo.
2- Its really true that after some time(a year?), the ear pads can change the sound of the headphones?
3-The versions of massdrop worth like the original version of sennheiser? Like HD 58x or HD 6xx vs HD 650 for example. Are better than the HD 660 s?
4-If sennheiser sell a version of Apogee on this version its because they believe on ess sabre solution right?
5-
