I bought my Apogee Duet more than a year ago.
If I had a choice now I would have gone with a USB one from another brand.
My Apogee Duet has had a noise and hiss problem since I got it. Other users have reported the same problem, but there is no simple explanation or solution (I've heard that it's use constitutes a "ground loop" and that using a three-pronged adaptor on power plugs may solve the problem.. but my country uses two-pronged). Apogee hasn't acknowledged the problem and still claims the Apogee Duet's sound in the superlatives.
I've learnt to live with it, since you can minimize the noise (that sounds like a fax machine) by putting the headphone monitor on max. and adjusting the amplifier volume. Still, since I don't use the recording function... the noise would make the whole thing pretty useless!
I would appreciate if anyone has had this problem.. and a solution to help!
