This is who services Kemper Amps in America. They are an independent company who do excellent work, I've had warranty (for other stuff, not the KPA) and general work done there several times. As such as in very high demand and at times can have somewhat long wait times.
When I returned my Kemper to Sweetwater, they told me they sent it back to Kemper, in Germany, for service, and to expect 4 - 6 weeks for a turnaround. Are you sure yours is in Dallas?
