I think the real point is whether the KPA500 will be an effective tool for the desired type of contact in the hands of a thoughtful (skillful) operator. I have enough faith in the design capability of the Elecraft group that I believe the KPA500 will be a "clean" amp. No GIGO either, if driven with a K3, etc. The power level should be more than sufficient for the best DX or pile-up, if the brain is engaged before the mike button is pressed.
Most of what I hear from QRO advocates reminds me of "road rage" or "extended magazines" in other contexts, e.g. poorly suppressed aggression. In a long lifetime of enjoying amateur radio, I have had the misfortune of living near hams who ran a Texas KW with excessive speech compression, or ran an early VHF/UHF amp of the "linearized" variety and who managed to take out an entire band. I recall a summer VHF Sweeps in which a group on Mt. Monadnock, ~50 miles airline from me, made the entirety of 2 meters unserviceable. Of course, voice operators are not alone to blame...one only has to examine some of our south-of-the-equator brethren running BPSK to see truly excessive bandwidth consumption. One or two of these BPSK'ers routinely take out the entire 4-kHz (self-imposed) PSK segment on 20 meters at my location.
