I've always had, and always will have a speaker system, but for me there are plenty of times when headphone listening is still preferable. Not SQwise mind you, but necessity wise. Speakers only topple the headphone system at higher volumes for me. Drop down to a low intimate listening level and the and the distance starts to narrow.
But yeah, there's no beating a good speaker setup when you can turn the volume up. One can't truly understand soundstaging until they've heard a great speaker rig.
