Headphoneus Supremus
I like the look of the Phonitor. It's esthetically pleasing. It also has interesting features like crossfeed. And it probably performs well based on many reviews. I was even willing to put up with the issue of the label paint wearing off considering the overall good build quality. But given questionable and confusing measurements from the official sourses and lack of a clear, meaningful, and adequate response from the customer support, I am not sure I want to deal with this brand and this particular product anymore. I am now leaning toward another brand, probably Violectric. Some reviewers say they prefer its sound over the Phonitor.
I came to the conclusion that the Phonitor XE is designed more for mid or high impedance headphones and less suited for low impedance headphones.
I have amps from both companies. The Violectric has a better build, it feels more solid. But they have some operational quirks and are getting away from balanced inputs, and don't have one with two pairs of XLR inputs (AFAIK) so I bought a Phonitor. I don't know that you want a Violectric for low impedance planars any more than you want a Phonitor. If you have the space, I'd suggest an Audio-gd amp, which have more inputs and a better build and power suppies than anything I'm aware of from SPL or Violectric or most other companies. They're beautiful in a garage-fi sense. I love the industrial build but that might not be for everyone, and they're not desktop amps.
