I recently purchased Audio-Technica M50s and love them. However, I am intrigued by the other postings on this forum regarding the various Beyerdynamics and the HD598. I am going to keep the M50s, but also want to buy another pair of cans. I assume I could purchase the HD598 for a better sound stage to specialize in indie rock, acoustic, and other music outside of dub step and electronic. I would maintain the M50 for this type of music. That being said, is the HD598 my best option, or are one of the Beyerdynamics my best bet? Thanks for your help!!
