Dear Clipwingcub (sorry, couldn't find your name).
Just wanted to clarify one item, the PAR100EX has Bluetooth where the PMA5000EX does not. The only loss of capability are the number of switched inputs! Otherwise, they are very capable audio panels. (note: the MAP of the PMA5000EX is $895 while the MAP on the PAR100EX is $2295, making the difference less than $400, when using Aircraft Spruce's M760 price of $1081.
I also think the pilot will find operation of the audio panel (as an ICS, audio controller, and radio controller) very simple, and that is what we have been told pilots are wanting. Capability without complexity.
