The result and quality of the Cortex: total crap !
Not even a shade of the Kemper !
Well... There is more crappy Profiles, than excellent ones. It doesn't make Kemper a bad unit. We must agree, that this QC clip wasn't a actual sound demo. More of a proof, that the actual unit already exists and it does have few amps etc. and actually the userinterface looked well finished and working already.
Having played Neural DSP Plugins, I have no doubts, that this unit wouldn't sound excellent.
Dynamics for example should be more than great:
In most cases, Soundcloud uses a bandwidth of only 128 kbps. As a result, what you hear isn't free of artefacts, especially the high end. For critical listening and also product comparison, please keep that in mind. Users who setup a comparison should use linear wave files and supply dropbox links.
