About the 4X, even 76. I have them side by side, through the same mixer and I just feel the 3X is much more powerful in its beauty. I have tried and tried to set this thing up and still not overly impressed.

The 4X has me thinking in a different direction. Maybe unload and get something totally off the wall.....

I'm almost willing to trade for a NEW 3X76 and then I can have a backup for my aging one. I'll wait for the 5X.

Back to work on it. Hopefully I'll see the light, dunno?
