Can the group tell me how Collins Radios rank as far as quality compared

There is no comparison to the audio quality of Collins, it is so vastly
superior to what you hear from any of the other manufacturers. That was
my experience using a set of ProLine that Ohio State has in their
Duchess, multi-engine trainer.
