Oh I miss my headphone rig sometimes, I still have a portable rig but the SR-80 ain't good enough. I just need a decent headphone amp and headphone.
I like the speaker rig very much, but with heaphones there are more details revealed.
Speakers are great when you want to move around freely, they are open air.
The bass is much better, especially with a subwoofer.
But when you want to listen detailled, you put your headphones on

I believe you can't compare cans with speakers (it's like appels vs oranges).
