In some conversations I had recently with a tuner expert, what emerged was how designing a good MPX circuit involves doing several things well at the same time without having them interfere with one another. For example, it was pointed out to me how important it is to maintain the phase relationship of the 38kc tone and the composite signal across the audio frequency spectrum. Otherwise, you can end up getting stereo separation only within a narrow band. Again, this is what I was told, but the story I got was that some of the less successful attempts at MPX units only gave stereo separation a bit above and a bit below 1kHz. The patent for the EICO MX99 actually goes into the importance of phase and separation at some length. It seems to be why the MX99 has a higher tube count than some others.
