Spdif question... 
Is it possible to adjust the SPDIF level during recording?
Reamping is no problem and the quality is ok, but in Reaper the SPDIF signal is rather weak... (the original recorded Kemper SPDIF ouput gitstudio >scarlett 6i6 SPDIF signal)
When reamping it is possible to adjust with SPDIF volume...
But I think that a "hotter" SPDIF recorded guitar signal would be better...
You're asking for a hotter "amped" signal when recording, i.e. not for the DI track?
You can adjust the spdif volume in the output menu.
Better yet (if the signal is not freakishly low): adjust the monitor volume 
For the di out the level does not effect the signal. Use distortion sense while reaping maybe?
Increase the SPDIF volume in the output menu.
Try setting Clean Sense to a higher value.

It is the level of the SPDIF (output SPDIF= gitstudio) that should be a little higher I think...
The dry SPDIF signal in Reaper is not very high...
Reamping is fine... but I read in the fora that the signal in the DAW, going to the Kemper SPDIF input should not be weak for good reamping results...
The SPDIF volume is on max... 0dB...
I will try distortion and clean sense... 
Thanks for the help guys! 
This should help:

Clean sens is the parameter which alters the "gitstudio" signal. But there's no reason to have it very high necessarily. You can do you gain staging with the "reamp sens" parameter. If you set that to the opposite value of the clean sens, the result should be the "authentic" one. see the chapter on reamping in the reference manual.
On the prints screen of Reaper you can see that SPDIF signals 3 & 4 are not very high...
With the "reamp sens" you can adjust the signal when it comes back from reaper into the kemper...
The SPDIF volume, which you can use for recording the SPDIF (coming from gitdtudio) is on max...
I must say that I'm quite happy with the reamp results, so I don't think I have a big problem here...
Just to be clear we're in agreement - the spdif volume in the kemper's output section has no influence on the DI signal through spdif. That's only affected by the clean sens.
