Got to run the Rupert Neve RNDI through its paces last night at rehearsal for one of our big yearly conferences...
My assessment so far is that it is a
very true DI. True to the exact signal you send to it. I don't know a lot about the details of the circuit inside the RNDI but I do know they make their own proprietary transformer as well as class A discrete FET amplification electronics.
I've read that you can send a 1000W amp signal to this thing and it has the headroom to handle it, given you load the amp with a speaker or load box with the thru output. I think this makes it super powerful in the instance you did want to capture true amp tone before it exits the amp and goes through more circuitry.
The low end was extremely tight and well defined, but clear.
I think
clear is an adjective that is synonymous with this DI. It is very pristine and doesn't make your tone pretty or add any flavor - but for me, that is the point. This is probably the opposite of a fancy tube DI, which applies lots of tube coloration and saturation, such as the Noble or REDDI - I think those are meant to accomplish a totally different end.
This is the setup I am using:
