I tried them out yesterday. Spent 6 hours A/B testing with the Heddphone, Lcd-mx4, & Solitare-P from a Kann Cube as the source and the T+A HA 200 Amp. This is indeed an excellent headphone. It makes the Heddphone sound sluggish and muddy in direct comparison using the same source and Amp. The MX-4 sounds a little beefier but the Solitare-P has a presentation that is wide with taut refined bass. It's enjoyable with bass heavy music but versatile enough to be an outstanding listening experience with all genres of music.
