different sound cards sound different..?

[hoogli]

My laptop has integrated (16 bit) sound. I-Doser hasn't worked for me on the laptop, so I tried it on my desktop (24 bit sound card). The same dose sounds different! Is that possible, or am I just hearing things?

...wait a minute, it might be because I have a cold right now and my ears are all stuffy. Then again, I listened to Holosync (another binaural beat thingy) today and it sounds the same on both the laptop and desktop and both sick/not sick. I'm guessing that when I-doser renders sound it does so differently with different sound cards, but since Holosync is a recording, it makes little difference.
