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.
I could not even use Kemper if not owning my Friedman BE100 and Mesa JP2C etc.. and not making my own specific profiles ! I went thru all available profiles on the net and not even one sounded the way I setup my Friedman and other amps..
So for me Kemper is just the tool which let me leave my heavy and fragile amps at home and use their DNA on stage without worrying about bad tubes and weight..
Of course it's maybe 90% or little more of feel of my tube amps live on stage, but close enough to be happy and inspired..
And no.. For me tube amps are not dead for sure.. I still need them if I change my mind or taste, and go to my Friedman or Mesa and set up deferent stomps and eqs and do new profiles and use them live exactly the way I love it to be
