hi, im currently using Beyerdynamic T70. Source is Sony entry level sacd player into Govibe peak hp amp. I'm considering an open can. I love Bon Jovi's song. I love drums. i listden to some vocals and acoustics. But my main objective is comfort as I want to listen to hours using the hp. I am considering the following cans: not following order Grado Ps500 Hifiman He-5 Le Alessandro MsPro Shure 1840 Audeze LCD 2 Sennheiser Hd600/650 or any other that i didn't think of. Thanks!
