I haven't messed with Hamtronics repeaters for about 20 years, but at the time they specified coupling speaker audio, and their repeaters sounded really flat and clean.

Distortion is not the only issue in using speaker audio as repeat audio. In many cases there is additional filtering in the speaker audio chain that can degrade repeat audio. In the end it has a lot to do with how the radio was designed. I once built a barebones system using a GE MVP with speaker audio going straight into the mic input using only an 8 ohm load resistor, coupling capacitor & resistive divider to get the level right. It did sound quite good, but I suspect this is more the exception than the norm. Bob NO6B
