The powercube is definitely a ham amplifier. I know of at least one owner who is very happy with the one he has but, then, he only operates SSB.
Most amps that use relay T/R switching (and that is *most* amps) do the clickety-clack thing. I know of failed relays that could not take the abuse. Your solution of using semi-breakin with an appropriate delay is the only way to avoid this problem. With my new KPA500 I no longer have that problem but, with my previous Tokyo HyPower amp, I used a homebrew PIN Diode switching system to do all of my T/R antenna switching with all solid state circuitry but that is not a trivial exercise.
