<font color='#000000'>The Yamaha does have the sub output. I had an old Onkyo that I never liked from the day I got it home. It was the most reliable receiver I had ever owned, but had to add an eq to get the sound I wanted. It was underpowered, and I am sure if I had spent more I would have been more satisfied. I replaced it with a Yamaha rx-v1400. These units, that being the 1400 & the 2400, are awesome. You can have 5.1 now, and they have all the goodies to go 6.1 and 7.1. They also have an eq built in. For me, I like my treble a little higher than flat, & I like to bring the mids in the vocal range down below flat. It is just a personal preferance. I was pleased to have this feature. I would describe the Yamaha sound as less digital, and more realistic.
Back to your question, the receiver will output the lfe signal during 2 channel stereo. Also, I went with the 1400 because it cost $200 less and is only a little less powerful, 110w x 7. IMO, that is plenty!</font>
