Hey all,   I have a decent sound card, soundblaster titanium fatality--will I still need an amp for something like the Q701's?   Thanks!

It's hard to explain to people exactly what the effect is, and frankly I don't know how or why it has that effect. I usually give some odd explanation like, "it lets some of the sound escape to create a better/more realistic sound stage." That's basically what I think it is, and how I imagine it...

I got my HD555's about a 5 months ago to replace the ATH M-50's I thought were stolen. (Turns out they weren't, and recently turned up. I only use them when I really need bass, otherwise the HD555 is easily better.)    Anyway, my ears have gotten spoiled and I want better headphones. I love...
