Any reason not choose an Apogee Duet?

My new mini mac arrived this week so its time to get serious about a DAC. (If you've thought about making the plunge, there are good deals at the Apple Store Clearance section)

Is there any reason not to select the apogee duet? The price is about 1/2 of what i'm willing to pay... and it provides a good ADC converter by all accounts.

My biggest worry about buying without audition is bass response. I just can't live with a forward sound. I need bass that I can FEEL.

Thanks in advance for any feedback or suggested alternatives.
