lamm lp2 loading question


There are many reviews and people here that refer to the Lamm LP2 phono preamp as having a MC Load of 40ohms. However, the Lamm website lists it at 400. 400 ohms would be rather flexible but 40 ohms would not be for most cartridges. 40 ohms seems awfully low for the only setting. Can anyone explain the discrepancy?

My understanding is that Lamm has 1:10 SUT inside so its natural impedance would be around 400 ohms. So unless Lamm adds loading resistor or something, 400 ohms would be more likely than 40, I would guess. I am still a bit confusing about SUT and loading myself :)
