Opinions on Apogee Duet performance

I've got one and use it to listen to music through my headphones. Aesthetically, it is beautiful to look at and beautifully built. It has a wonderfully slim form factor and partners any Mac wonderfully.
As for sound, it is wonderfully smooth yet at the same time highly resolving, it also projects a very realistic sound stage with my headphones. I find listening to it for long periods totally non-fatiguing. At its price point it is nigh on unbeatable in my opinion.
Highly recommended.

Cfcjb,
Have you ever tried it in your big rig? What phones are you using? I will be using a pair of HD 650.

Rrboogie, I haven't placed it in my main system but I would not be surprised if it compared very favorably to my Resolution Audio Opus 21 CDP, which in and of itself is a great CDP.
The headphones I use for listening are Audio Technica ATH-W1000.
I used to listen through a Red Wine Audio modified Ipod and Ray Samuels SR-71, both excellent products and truly portable but the Apogee/Mac combo beats it. It really is that good. If it were to be produced by an audiophile company you could comfortably triple the price.

I am even more eager to hear one now! I have emailed apogee with some technical questions and if I can make it work in my system this will be my next dac.

Thanks for your reply!
