Ok i will review first! Yes its worth it

Is it worth it? Hell yes it is. Can i drive this with my phone and enjoy it? Yes you can!!!!!!!! you read that right. Does it sound better with a good DAC and more power? yes it does. Whats the difference in tuning vs ALL the other planar offerings- plain and simple its clearer, more dynamics and sounds better than the other offerings. does it have bass? yes it does very well actually. Will it benefit from tuning? user preference so i lean toward yes. Should you buy this if you looking for a clear resolving planar headphones that a very flat frequency response that is very easy to listen to with out eq-ing the living crap out of it? Hell yes you should buy it. once again YES,YES,YES you can use your phone for playback and be very pleased with the results
