I've been listening through this
amazing dolby setup through the GR07:

Honestly, when I'm listening to vocal music that is emotionally charged, I prefer the intimate "in your head" presentation that headphones provide, and especially the slightly forward types. I wouldn't trade such an experience for even the best and most expensive/advanced speaker system/setup. When the singer(s) sing, I'm them, and they're me; or, they sing along with me, and I with them (albeit in my mind, not aloud... I will keep it that way lol). There is nothing like the experience of walking home a mile away down the sidewalk during a cold, lonely night, with snow (or rain) all around, and you're gently pushing along (hopefully in warm clothing!); and you're listening to a sad, moving love song through IEMs. I've had that experience and similar experiences multiple times, often outdoors, and I just can only imagine a surround-sound presentation would take away from the emotional intimacy of such an experience. Being sung to, and singing with, are two very different experiences. In the latter, you often feel like
you are the music, as opposed to being
surrounded by it.
That said, when I'm listening to a "fun" song, or I want to be serenaded, a great surround-sound presentation much like the one I'm listening to, which I discovered in the thread above, is the preferred presentation. Just thought I wanted to share that nice little discovery, and my thoughts about the joy of headphone listening. ^_^
