I know this thread has been resting a while, but since Radial is soon going to launch their DInet-Tx Dante DI-Box, I just couldn't stay quiet.
If Kemper incorporated the DANTE Protocol in the KPA it would be possible (with the existing hardware, a switch and the DI/Box) to run the Remote and the guitar signal over one cable. With the DInet-Rx you could even ad an effects loop for analog stomps over the same cable.
Oh, please Kemper-Folks, DANTE on the Kemper would be so cool.
P.S. The greatest thing for me would be if the output signals of the Kemper where on DANTE, too. This would mean one cable total for in and out. Awesome.
