[Elecraft] KX3 and KPA1500 compatibility

[Karl W Hubbard]

I have a KX3 and a KPA100 amplifier but despite various attempts at verticals, end feds, OCFs, and loops, am unable to call anyone, especially on Elecraft 80 m Sunday nets on 3.784 or 3.786. Reception is adequate with most 5/8 or 5/9 and verify against the call- in list. A lot of people seem to get by with a KPA 500 but reception is not as solid as those running the legal limit. My understanding is that the KX3 is compatible with the KPA 500. What about the KPA1500?
Question: Is it possible / practical/ safe to daisy-chain a KX3 to a KPA100 and drive a KPA1500? 
Thanks and 73,
