In my limited contact with SPE amps, I'd say the Elecraft amps are 
substantially cleaner. One of our neighbors was getting reports of a 
dirty signal on 6M, so one of the guys went to his QTH to help him 
diagnose and clean it up, while I watched on a P3/SVGA. Part of the 
problem was that he was running at low voltage; sidebands dropped by 
about 6 dB when he switched to high power (he was only running 
400-500W), but sidebands were still very nasty, looked like noise rather 
than the small but pronounced peaks spaced in 300 Hz increments from 
N5KO's FT8 signal. I had one for a few weeks, but dumped it because it 
wasn't very clean.
