Ears hurt when listening after changing speakers

Your room is getting over pressurized and  bass loaded. You can move them out into the room, or you can purchase a ton of bass busters.

I attribute that to my excellent hearing.........lol

I would add one more thing. The kind of fatigue you describe could also be caused by bad or shorted interconnects up stream, causing a real low hum. 

That beryllium dome could be making you a little jumpy. I had been a dealer for Merlin's until I realized that the Esotar tweeter was so bright I couldn't stand to listen.  Sold the demo's and discontinued the line. I never want to let a customer suffer through that or myself.

I am sure you could.
