I have tested on a ge mastr II and mvp, Motorola m120, maxtracs, and radius models, msf5000, and an r100. The r100 did sound better on simpleusb and it did show on a graph that way as well, but it also wasn't using true discriminator audio. If you align the Audio that way it is supposed to be you will not see a difference. I must say though that I have only used true discriminator audio so if you are testing something else then the findings may be different.
