They arrive tomorrow. Really looking forward to the journey. I owned Yamaha NS-1000M Studio Monitors for years after working at Harvey Electronics and Rabson's both in Manhattan. These were the Beryllium dome parents of the NS-10M. I've always been enraptured with Yamaha's musical roots and they way they crossfeed the collective expertise and experience of their engineering departments across their product lines.
My good sir, if you get a good fit/seal, you are going to be enthralled with the sheer musicality of the EPH-100. Congrats! Let us know what you think?
