Should i get HD800 or HD800S for my Sony ZH1ES? Will ZH1ES warm and smooth character be enough to tame the HD800 harsh and revealing signature? Esp the 6khz? Or the HD800S would be a better bet (at greater cost...)? I know it would be good if i can test them, but currently there are no places here that i can test both can together with the amp. any thought would be greatly appreciated.
