Peter, I recently switched from a Moerch DP-6 (with 12" Red wand) to a Triplanar, each used on a Galibier Gavia. In my opinion, they are both excellent arms and, with the right cartridge, are each capable of top flight performance. It is hard to provide helpful capsule descriptions of the two arms because the sound of the Moerch (like many other arms) will be affected so much by the choice of phono cable. The Triplanar has a dedicated cable so it isn't subject to that variable. With that major caveat, I found the Triplanar to have slightly greater inner detail and a more solid low frequency foundation. Of course, the Triplanar also has more convenient adjustments for VTA and cartridge alignment.
For someone who prefers to listen to music rather than obsess over tonearm adjustments, the Moerch can be quite satisfying. If you are the type who wants to adjust VTA for each recording, the Triplanar is clearly the way to go.
