tube di box with the kemper

Is this with a profiler?
Why?

Because the KPA sounds harsh and digital...

Anything you add in front of the KPA has the same effect that it would have in front of the real amp. Some people uses tube OD in front of their tube amps to add something that their amp is cannot do by itself. IMO, you don't need that with the KPA with all the rigs and stops available.

I don't think this is with a profiler. The Palmer stuff is reportedly very good, from the little information I could find on the web. Made in Germany.

This DI box is apparently "voiced" for guitar, as opposed to what a conventional DI box might do with a signal. The tubes probably excite the signal in a good way.

I bought the Kemper precisely because it gives the live feelings of a tube amp. Don't know about this particular DI but my experience would say to keep your money and enjoy the KPA alone!

@ Foo: are you somehow unsatisfied with the sounds you're getting?

In the years I've overcome my old urge to just "have more". Not saying this is your case, by any means! My GAS is made so that it pushes me to look for solutions before (or even without) having problems...
Basically, I've discovered that defining your needs/likes will clearly show you your way. As long as I don't see a clear need/like, I go on focusing on using what I have at its best, and my personal performance as a musician.
Just a thought, maybe OT as well
