"Transceiver and amplifier manufacturers will continue to give us poor
IMD for exactly as long as the major equipment reviewers (ARRL, RSGB and
DARC... but mainly ARRL) continue to remain silent."

But, these equipment reviewers are not entirely controlled by the advertisers.  
They are also controlled by subscribers, and there has been no significant 
demand by them.  A manufacturer could produce a superior product and then 
promote those qualities.  The problem is that to do so would admit that their 
lower priced models were inferior, and they are not willing to do that.  
Someone could sponsor distortion measuring events just as the frequency 
measuring events we had for years.  

At this point, there is only a handful of people "demanding" cleaner signals.  
Some contest stations actually want dirty signals to give them greater 
"clear-channel" bandwidth.  

And, even if the magazines "raised the bar", that would not necessarily 
improved things.  The breakthrough may be when one manufacturer begins 
marketing their low end transceiver with a -35 db IMD rather than a -25 db one. 
 That would give a distinct marketing advantage.
