Need suggestions for another pair of headphones (Have Sennheiser HD600)

What are you powering them with? As far as open, well in all ways my preference is the Sennheiser HD800. With lots of natural sounding power they are spectacular. You can see my system under my ID.

Other headphones I have are Focal Utopia, Beyerdynamic T2, LCD2, Ultrasonde Edition 8… and a few others.

The sound of headphones are strongly dependent on the streamer, DAC, and particularly the amp. I was not blown away my the HD800’s until I got the Woo WA5… I think it has more power than the Felix and I am guessing maybe more natural sounding… well I have Takatsuki 300B… but this completely took control of the HD800’s and made them magical. My Sennheiser 800’s do not sound at all analytic… with my electronics.

Everyone has different tastes, so no solution fits all. But I had to fiddle (experiment and invest heavily) in my electronics to get my headphones to sound right. I probably have 5 - 8x the money invested in electronics and suddenly all of my headphones sound great. [my Beydynamic T2 always sounded very natural… although not open]. My Focal and Sennheiser actually sound a lot alike now… with the difference being the openness… (because the Focals are only semi open).

By the way, I went as far as importing an amp from Germany in my quest to get my headphones to sound right. I have gone through a lot of equipment to get here… but for me, it was mostly about the electronics.

Focal are very good sounding… I would say neutral and easy to drive.
