Almost any portable amp can get most headphones to produce enough volume. Opening them up is another thing. I think you need far more than portables to find out what they can do, regardless of how exclusive they market themselves.
I listened to the planar magnetic HE5 on the Matrix. It sounded good and went loud on top whack, but not ear damage loud. It really felt like the phones were being restricted, and had far more in reserve than the matrix could give it.
