Purchased at Amazon in hope of obtaining some "free" gain for dynamic microphones.
Admittedly, I was lured by the comment made in the name of Ramesh Singaram:
Clean gain? Initial voice recording sounded distorted, so I decided to measure the device.
All done via loopback on Audient ID4 mk II using balanced cables and main (speaker) output.
Audient preamp is turned off: knob is set all way to the left, meaning it acts as the line input.
For comparison, raw ID4 measurements can be found here: https://www.audiosciencereview.com/forum/index.php?threads/audient-id4-mk-ii-review.35017/
1K sine
Look at these harmonics...
Sweep
Hmm... What if it does not like loud signals? Let's reduce the output:
Better. Still far from "transparent", but better.
Multitone 32 (averaged 5 times)
Same with the signal reduced under -20 dB
RMAA
Noteworthy graphs below.
THD+N
IMD
Numbers speak for themselves.

The Klark Teknik does a great job of boosting the signal without introducing anything adverse - not that I can hear. A clean gain.
