The LFE signal in this instance only goes to the sub, along with any bass from any channel set to small. If I choose "LFE+THX" then each of the fronts gets it's own full range signal, and the "left bass" (anything under 80 Hz) stays in the left front and the "right bass" (anything under 80 Hz) stays in the right front. In 5.1-channel, using a DVD, if I have my sub turned on in the setup and my front speakers are set to Large, I get to choose where the bass gets routed. Fronts handle the full range and there is no choice of "LFE+THX" or "LFE+Main".
In 2-channel, using a standard stereo signal (from a CD), if I have my sub turned off in the setup then the front speakers default to Large, and of course you get no bass from the sub. The choice of "LFE+THX" or "LFE+Main" does not appear if you choose small for the front speakers. In 2-channel, using a standard stereo signal (from a CD), if I have my sub turned on in the setup and my front speakers are set to Small, I automatically get bass from the sub which has been routed from the fronts (everything under 80Hz as my crossover is fixed). There doesn't appear to be any difference soundwise. In 2-channel, using a standard stereo signal (from a CD), if I have my sub turned on in the setup and my front speakers are set to Large, I get bass from the sub and the fronts regardless of whether I choose "LFE+THX" or "LFE+Main". So if Denon has changed anything in the past couple of years, your results may be different.
This is based on my experience with my receiver. I have a Denon 4800, so I'll throw my 2 cents in as well.
