It does not have to be a tube unit to take advantages of different stages in the preamp. The Great River for example... It just adds a little flexibility to the range of what you can do with many of the preamps by having an output attenuator.
True, but then there are many quality preamps that don't have an output attenuator: John Hardy, the Pacifica, API 512, Wunder PAFour, etc.
I'm making a chart to try to keep track of all the information on each pre I'm considering so I can see that good and the bad all in once place. Going on the presumption that I like the sound of all of these units, here's what I'm coming up with so far, and I think they're in the order of preference; although the Hardy and Demeter are probably even in my head. The MP-2A gets to the top because of the 4 tone options. I thought that might come in handy considering I won't be buying a second dual-pre any time soon.
