I checked the Ins/Outs and have them set as close to the same barring limitations between platforms - PAD is off on my LT - not sure if that's what makes the volume so awesome.
 
	 
 
	I played the XL live this weekend and the volume at 80% made the house happy, where LT is usually at 50%. Other than having to dial the volume so much higher, it performed very well.
 
	 
 
	Later, I got a second USB B cable out and had both up in HX Edit. No revelations as far as volume, but did discover that my cab mic, delay, and reverb were all slightly different between LT/XL due to legacy, stereo, and such. After correcting, tone is more consistent but none of that improved the difference in volume.
