I had a SPE 1.5K for a couple of weeks. It struggles to make 1.5KW on all bands and on some doesn't make it. At 1.5KW there is around 2dB compression. It's great up to 1KW.

I've had the KPA1500 for about a month now. It makes 1.5KW with between a .5 and 1dB on all bands. It's more money than the SPE, but worth it. And of course excellent support from Elecraft. Integrates well with my TS-990.

I've used a KPA-500 enough to appreciate the integration with my K3S. I am using an SPE 1K-FA right now, and it's nice, but required me to construct a custom cable to use it in the most integrated manner. The 1.3, 1.5, ans 2K-FA require the same thing OR one of the new serial boxes mentioned in the last couple of days. The KPA-1500 offers both the integration of the KPA-500 and more power than the 1.3K-FA.... Better to look at the price comp between the 1.5K-FA and the KPA-1500. I like the separate power supply on yhe KPA-1500. BOTTOM LINE: My next amp purchase would/will be a KPA-1500.

In consideration are kpa500, spe 1.3k, and kpa1500. Obviously increasing In cost as we gain more capabilities. Any feedback from the group? I was expecting to see more kpa500's for sale but haven't seen many.
