In regards to your statment:
"You will never "feel" the bass from a headphone. My advice would be to integrate the Buttkicker with your headphone system, and get headphones that extend relatively low; the PRO900 and HFI-2400 should both satisfy that imo. Then you'll have tactile feedback + headphones (and the whole sub + headphones or tactile LFE + headphones thing has been done before, if you dig around the computer audio section there's probably some threads about it and hooking it up; or I can explain if you're stuck)."
Reply: I already have the buttkicker synced with my current headphones and I love it, except that I wish they had better bass. And what you explained is exactly what I meant when wrote:

That is why I was interested in a great bass headphone that still keeps a decent sound stage. And the Pro 900 fits that build from reviews. I think I will like them....Its a bummer the 2900 is so expensive right now. Maybe one day I will be able to hear them and compare them with my Pro 900s. Can't wait to get them in the mail later today!!
