The league also went on to say in the review that the TS590S has very good IMD performance for a 13.8volt radio. They obviously did not look at their own review of the FT950S which had a much more impressive -35db below pep. This was also for a 12 volt radio.
Just was looking for both rig reviews at RSGB. There the numbers for all 10 bands are available. In avarage over all 10 bands the TS-590 is -34.4 dB IMD3 and the FT-950 -35.1 dB. That difference of 0.7 dB is not appreciable.

Yes and then there is 590 spec's on receive which has a much better front end than 950.
