RNDI : Excellent DI not only for bass but also for analog synths / drum machines

I bought it with the idea of using it as a complementary DI to my REDDI, to track vintage / modern analogue synths and drum machines through different preamps.

I needed something that would be rather on the "clean" side comparing to REDDI, more transparent, something that would handle fast transients much more naturally. Being a devoted user of a tube DI, I was surprised by RNDI with its very elegant sound across very wide frequency spectrum, nothing was missing from the signal, I did even a comparison between RNDI and a tubeless DI used in one of the best converters on the market, super transparent device with amazing preamps, built in UK. I configured two channels: one for connecting instruments to the converter directly using its DI and its gain control, the other one with RNDI and the converter's preamp.

Initially it was very hard to find a difference after level calibration but I found that RNDI really shines when the synth sound is quite harmonically rich, poly modes with fast envelopes. Same with analog drum machines. To me, some elements of the sound are more apparent and detectable. It definitely doesn't hide subtle details in midrange or lower. As expected, low freq. range is more than solid. Absolutely amazing.
