Then you're all set. Spend your money on something you really need. For example, how's your monitoring?

Why do you think the Firebox sounds better than the Audiophile? Both have a frequency response that's plenty accurate, with distortion and other artifacts well below what's audible. I would expect both sound cards to sound exactly the same. In fact, if they
don't sound identical, one of them is broken!
