Home audio speakers are designed to make music sound good. Monitors are designed to tell the truth. Audio speakers produce frequencies used in music. Monitors produce the wholw audio spectrum., including hiss, hum, rumble, everything that sucks. If monitors sound really good, either they aren't very good monitors, or you have a righteous mix. Generally, mixes done on headphones sound pretty good- on headphones. The lack of crosstalk is a killer. It skews the pan on every signal. When I play something on speakers, my left ear doesn't just hear the left speaker, it hears both left and right. And the difference in time between the arrival of those two signals is what tells me the left speaker is to my left. Headphones are like an MC Escher painting. It's a picture that cant exist in the real world. So then I start playing with the panning to simulate reality, but it doesn't work. I do a lot of stereo recording, and I find mixing with cans to be pointless.-Richie
