Ya know all the lights in the world won't save you in the end.
I do have a great sound card to boot... 24 bit 96 KHz... even that aint goin to get me to the finish line...
In the end it comes down to being able to hear what it is you've done.
If you don't have some decent monitors (no not the one your looking at, the ones you should be listining to) you will never get it. Even a deaf person with a desent pair of monnitors can hear. If what your are listining to are called speakers, throw them in the trash (or religate them to a secondary). Many times I see folks posting "I lisended this on this system and on that system to no avail".
