I downloaded the manual to your r500. When a soundguy insists on plugging you in DI, tell him to USE THAT XLR OUt from your amp. Take a look at the block diagram in the manual... with the switch in POST the signal will hit every part of your amp except the power section and it's limiter, then go to the xlr out. In PRE the equalizer will not effect the xlr out BUT (and this is huge) you do get the tubes and the effects loop going to the xlr out. If you like the sound from your amp, tell the soundguy to use your build in DI.
The sansamp bddi is a preamp. Bass>sansamp>board is essentially the same as Bass>r500>board (via line out). But your amp does it better because it actually has a tube, whereas the sansamp just emulates a tube. And of course, you like the sound of your amp, so that makes it better too.
Sidenote: My Ampeg B2R's xlr out has a pre/post switch. When in Pre, the signal chain is input jack>-15db pad>xlr out. the point being it skips the effects loop. So, check your manuals folks, block diagrams are useful.
If your Mark Bass has an XLR out - I would just use that. I've never seen the point in using a seperate DI box of any sort if the head has a dedicated out. Seems pretty redundant. If the soundman complains about wanting a Pre-EQ signal, I know on Ampegs there is a pre/post EQ switch that routs your signal to the XLR accordingly. Not sure on the Mark Bass.
