I did, i put a CD in my PS3 and optically to my pioneer 
7.1 system for home audi, and it did sound a bit better,
but I didnt haev the same bass disruptive soungs on CD to 
try, so I will do that. Irregardless, i think i have to get the 
amp, and thus still have to figure out this optical in/out on a
card that will work with linux.

320 cbr mp3

i have been thinking can it be anything else? but there is so many
google hits
with HD650 (or HD60) and head phone amps and so many people swearing by 
having to have them.

And also the songs in question sound fine on my HD570's which are not as
high imped. So it does seem to point to the sound card failing on 
generating the energy to drive them.
