Well, the DP6 is not quite a unipivot. I was researching both Graham and Moerch arms when I was upgrading my tonearm, and went with the Moerch because it seems that the Moerch arms do bass better than the Grahams, which seem to have a reputation for having lighter bass.
But these are my impressions just based on internet research, not a direct comparison.
