Hi rcasio44,
I've had my MXT for almost a year, and I know exactly what you are describing. When I turned the gain up into the plus area, I had to turn the volume down to avoid blasts on shallow targets. And, by turning the volume down, I was not able to hear the deeper targets.
After a couple of months of this frustration, I purchased a pair of Killer B's Wasps. I am glad I was not told they wouldn't work on an MXT. I am very happy with them. They work great.
