I don't think of the Phantom as a pure unipivot either because it is stabilized with the Magneglide system.
FWIW, I have a Phantom II and don't find it lacking in bass. I did think the 2.2, which is a pure unipivot, had bass issues. Its bass always sounded a little dissociated from the rest of the music in my system. I was able to minimize the issue with super-fine adjustments to the damping fluid but I could never get rid of it entirely. I don't find the Phantom II to have that problem at all.
Never heard the DP-6, and it may well have better bass yet. Personally, I couldn't live without fine VTA adjustment, but that's just me. Were I looking at Moerch, I'd be tempted by the DP-8, which is reputed to have fantastic bass and also has fine VTA. Way pricier than the DP-6, though. I think it's a very tempting arm.
