I purchased a pair of matching components from HeadRoom about 4 years ago. One of the features I use pretty much most of the time, especially with hard-panned rock music is the crossfeed circuit on the Micro Amp. It's the the point I'm reluctant to switch to another brand of gear is this feature. I was wondering what other possibly more experienced headphone users is what are your opinion of crossfeed features whether it be hardware or software?
