ok, this is a strange tip for a KPA forum
But see it like this:
If you are used only to digital gear - yes, there are a lot of users who never ever before have owned a tube amp ......
.. your eyes and mouth will be open when you play a great loud tube amp for the first time.
For the others (used to great tube amps) - even when you own the KPA - get a tube amp - in case you don't own an tube amp anymore.
There is a special feeling - sitting next to a great tube amp - the zero latency sound - the many nuances - the smell.
Even when you use this real amp only as a reference - how close the Kemper can get to the real thing.
Another reason is - you can profile this great tube amp - you'll learn a lot about the KPA when you start to profile an amp by yourself.
And one more reason - support tube amp manufacturers - without then would we have no great (new) profiles.
