DR X/- from multiple sources stacking?

[Trainz]

DR does not stack except in the case of Armor as DR from the Unearthed Arcana. AaDR does stack with other non-bypassable DR (barbarian DR, adamantine DR, etc.).

I KNEW I read it somewhere.

But is it clear that DR/- stacks with other kinds of DR/- ?

The basic rule is "DR never stacks."
The Armor as DR rules specifically state that DR derived from that rule does stack with other non-bypassable DR (i.e. X/-).
Unless the specific examples have an exception to the basic rule (such as Armor as DR) then DR never stacks. Dwarven barbarian defenders do not stack their DR, but they probably do need to seek mental counseling at the first opportunity.

Yes, but for reasons that are unrelated to his choice of classes.

His choice of classes may very well be related to his alignment change.

I though it stacks so long as its a Permenant ability like those granted by classes like the DD and Barb or feats . Things like Adamantium breastplates dont stack.
