Perfect speakers and the typical ham transceiver has a audio PA section with 20% distortion and the receiver is full of inband IMD.
Then you have ESSB stations trying to EQ mics and EQ the other stations poor receiver, the comedy shows goes on.
There are number of perfectionist in the audio community trying to get away from the "voodoo" science in the audio world and are
designing and discussing all aspects of good audio quality from a technical design perspective. They doing this not from an emotional
audiophool perspective. Many of the issues and problems are the same when applied to receiver designs and in particular the audio section of
the receiver. You can read about it on this link. As you can you see they discussing objective audio measuring and design.http://nwavguy.blogspot.nl/2011/07/o2-headphone-amp.html
When we have the same level of design perfection in ham receiver RX audio chains then we can maybe talk about good audio quality.
For the moment we kidding ourselves expecting perfection to come out of the speakers of the typical ham receiver. We dont have one ham radio transceiver
on the market that has a decent audio amplifier or headphone section that is free of distortion and IMD. Like ESSB you wasting your money on anything more than a motorola mobile speaker. This is easy to prove but the hams with the golden ears want you to believe their voodoo nonsense. Like the objective audio guys you have to put your money where your ears are and back your claims with measured data.
