This thing fantastic. Added a good bit of clarity and stereo separation.
The gain control with clipping indication is pretty neat,green LED blinks red if signal clips.
The wallwart that came with the preamp has some heft to it (unlike the switching phone chargers). So I assume there is a transformer in there which is always a good thing. I don't hear any power supply noise coming through. Clean sound.
As others have said, the power on LED (blue) is way too bright. I had to cover it with electrical tape.
The capacitive coupling (100pF, 200pF) adjustment and low-cut filter are transparent buttons with an amber glow when depressed.
In the attached video, the line out of the DJPRE II is connected directly to the camera mic input.
I definitely recommend getting this.
