"I am well in driving distance to visit Axiom. I am wondering if it is worth the trip up and see if I can do a blind listening test for the M80 vs LFR1100 and with/without the EP500 in the mix."

Absolutely go and visit Axiom. This is a big investment and you'll put your mind at ease whatever you decide. Ian and Co are wonderfull hosts and you can tour the facility. We won't even mention the scenery in the area...

Half of communication is listening. You can't listen with your mouth.
