These sims gave some interesting results. Be fore warned don't let common opinion interfere with the test results. I am changing component values to see how they effect Z matching and if they are needed for good performance. I have been told some components are redundant and unnecessary. I was also told the circuit simply will not work. I just testing the circuit with and without the "redundant" parts and changing values to see the effect on Z matching. I'll let the sims tell the story.
Anyway I found the results interesting and hope you do too.
