I'm fortunate enough to try out some great di box in the past few months. The classic Avalon U5 and the A-Design Reddi
These are both great recording gears that are famous for tracking bass signals.
Avalon U5 gives that clean and defined sound. The 5 passive tone curves are all very efficient. The bass sits right, and I found it better to bypass the tone circuit.
A-Design REDDI is the monster, I prefer it over the U5. The tone is that nice and big with plenty of headroom, the tube doesn't really colour the tone like my UA solo-610 tube pre. I guess the Cinemag transformer they use really makes that difference.
They are both awesome and can get the job done right. I personally prefer the REDDI
