The nice thing about DACs is that they are easy to ship and swap out. I'd get the Duet and another one. Sell the one you are less happy with and buy another one. Do this until you have found your sweet spot. I did this with about 6 from $300 to $2,600 and ended up with one that was $1,100.
Being able to swap out gear at close to purchase price is one of the great features of Audiogon.
