As all of you probably know, crossfeed attempts to simulate how our ears naturally hear music and sounds, by letting both ears hear each channel, like a 2 channel speaker setup. I have been using the ToneBoosters Isone VST plugin for quite some time, and it has a very natural crossfeed option I really enjoy. I feel like it only increases musical immersion, without many drawbacks. Subjectively, I feel like it is a good step closer to making headphone listening more natural, and perhaps has advantages over speaker setups since it doesn't have room reflections. How does everyone here feel about crossfeed? Also, are there any recommendations for good crossfeed plugins to try, or maybe internally built crossfeed on amps and dacs?
