I don't have the amp but would very much enjoy hearing comments from all
those that do have them. I might add I do have other amps and a KPA500 as
well but using it with an Icom radio for mostly 6m.

Just FYI, I got the Elecraft 100W amp in two or three weeks ago. At over $
1100 it better beat these other amps. It has a tuner but I also have the ATU
in the KX3 and two more discrete ATU's for higher power, balanced (PAL) ,
etc.
Have you tried the Elecraft amp yet ?

Another correction. HLA 300 (and probably 150) have RF sensing PTT and
automatic band switching. They also have decent IMD is not driven to full
output power. HLA 300 is about 25-30 db IMD when driven to 150-200 watts
(5-7watt input) and cost under 500 USD. No antenna tuner though.
