Can I Use a David Bray Line Out Box or Groove Tube DI for DI Profiling?

I want to do some DI profiling and I have 2 things in my studio that may be usable but I dont know. If neither then I guess I have to get another box.

First thing I have is this DI box. I doubt this would work and its only for DI for like a bass or something:

Then I have this David Bray LO1 which I think might work. It takes the speaker out and then converts it to a line signal:

Ill try it with the bray. Why wouldnt I be happy? Ill gladly order the KPA one if its best but I didnt think that it mattered as long as it worked.

Thanks for the heads up. Sounds like a mess. I really want some direct profiles bc I am using real cabs.

Question- On the profiles I download they all have cabs and the first thing I do is disable it. But how does the profile know the impact of the speaker if the profile isn’t merged or di at all? So I turn the cab off but it’s not a true di profile right?
