I have used SPE 1K  with my K3 for almost 8 years. I am now using SPE 1.3 with both K3 and KX3 connected for SO2R. No issues with integration at all (just coax and  3 wire control cable), cheaper then Elecraft, weight is under 10 Kg even with antenna tuner built in, SO2R with just 1 amp, 4 antennas switchable by the amplifier itself (another level of integration). IMHO KX3 + SPE 1.3 is the best combo for expeditions of field operation. I really like Elecraft but as far as amplifier is concerned  SPE is better for my needs.

Mine too. Normally, there are three amps on my desk -- two 87As for high power, SO2R contesting, and a KPA500 for 6M and instant on). For about two weeks, I've been running a borrowed KPA1500, mostly on 6M (but used it to work 57 of the 63 WRTC stations on 20M). It's a VERY nice amp. I had an SPE 1K for a while and really disliked it.
