It only really works if you have a headphone that has a too strong L-C-R image but the spaces between L-C and C-R are off to the back, which doesn't translate to believable vocals and guitars in front because even the drum hits can get pushed forward while other hits stay in the back. The end result will compress the instruments towards the center, although depth will improve the vocals might move forward even more. The stock Crossfeed on my Cantate.2 amp actually works well enough to tame the L and R image on the SR80 and SR225. On the HD600, where the L and R if you push the headphone forward a bit don't have this problem to begin with, so even teh Cantate's can be too much for it. Using it as a baseline I tweaked Neutron's to see if a more aggressive or less aggressive setting will improve it, but the first only made it worse and going the other way still compressed the audio in the center but not enough depth was added.
So basically, I leave the Crossfeed disabled. What I use Neutron for really is the EQ. It has all parameters imaginable that even a competition-ready car audio digital processor will not have all these tweaks. I can neutralize the excess bass (that I can still live with otherwise, but I would make it flatter when I could) on my ASG-1 with these, particularly if I use it with an Ibasso D-Zero. It's a little better than the S3's DAC in terms of overall tonality, but while its amp tightens up the bass, taming it a bit more just makes the ASG-1 better. On th HD600 I just cut a bit off the treble spike that shows up in graphs, and the treble gets a bit smoother.
