Agreed. Planars in general have fantastic Bass texture and detail, but they don't pack the same sonic punch as a bass oriented Dynamic driver. My HE500s EQ'd up very well, but they never really had the SLAM I was getting from some of my other Headphones. Getting a more powerful Amp really helped in that regard, so I am in complete agreement with you there.
