You get what you pay for. An active DI with quality transformers can easily
give a flat 20-20 response at up to +24dBu and with THD better than 0.1 %.
I'm getting that at +10dBu with a home build using the the transformer makers
recommended schematic, and was quite astonished to be able to reproduce a
flat-topped square wave at 100Hz with no visible overshoot.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

I'll keep it in mind and test it someday. The idea of a DI-box between
analog out from the sound card and input of the mixing console is
strange, but that's were the problem appears. Parasitic noise might
disappear, but transformers of a DI-box likely will have negative effect
to the sound quality. Is there a DI-box without negative effect to the
sound quality? Increase the volume and you will hear digital
noise from the analog IOs
of a card inside of the computer. Move the mouse and extra noise will be
audible, no MIDI is needed to get annoying noise. MIDI noise is very
silent compared to mouse noise, but there is some noise.
That's exactly the noise I'm talking about. With ground-lift it goes
away. At least it did for me.
