Where can I find the best definition or explanation for "Simulcast" systems like the Metrolinx system?
Thank you in advance.

In the context of P25 trunking, a "simulcast" is a collection of physical transmit/receive sites (referred to as subsites) which are all transmitting on the same frequencies at the same time, and together they all make up a "simulcast cell" or "simulcast site", which appears as one single site to radios/scanners.
So you may have 10 of these physical subsites across a county/province, and all 10 of those subsites would have repeaters programmed for the same 10 frequencies. They are all linked together so that anytime a radio keys up, the voice transmission will go out over all 10 subsites at the same time over the same frequency.

Just curious... Metrolinx is simulcast. They have the best sounding audio of anyone I can hear in the GTA. Why is that?
Is it a side effect of the simulcast, better equipment?
Many times bad audio can come from the local environment where the user is. IE trains tend to have a lot of background noise. Another big issue it the radios in use. If they have different firmware versions this can sometimes give wildly different sounding audio. The Firmware issue also applies to the receiver being used. All the current scanner FW has been tested by millions of users and there are no major complaints.
