^^ Mine is the Oade Mod version and yet I still insist on running external pres fairly often. Really depends on the show and mics whether I think it's worth the bother, though. With the 414s, I found I preferred the -44 internals to some of my external options. But that's not always the case. I think the Oade mod version is a good bit brighter and tighter, while the stock version is darker and a tad muddy. Hence you have to be careful running a brighter pre analog-in to the Oade mod versions.
That said, the SD box is lightweight and runs off my existing battery, so it makes it fairly painless to bring it along unless I prefer to use my smaller bag, in which case I'm usually running 2-channel with the M10 anyway.
