Scott Nixon's site indicates that he is in the process of revamping his USB line. I dropped him a line to see if he has anything in my price range.
I agree that I won't be able to afford true audiophile equipment in my range. Given that money is a real concern, I'm looking for that sweet spot of intersection between price and value. I purchased by Musical Fidelity B1 for about $200, and while it isn't perfect, it is awfully good value. My speakers ran about $600. As such, they have many, many shortcomings, but for the price they aren't bad.
Given that the interest in USB DACs is relatively new, I wonder if the next year or so will bring reasonably good budget audiophile products to the market. I am heartened by the enthusiastic reviews of the Vintage Audio Labs, the Keyes, and the Giga Labs Moon DAC.
I was mentioning the Pacific Valve Company as they have a US-based operation out of Chicago. Perhaps that might have quality control / customer service implications?
Best,
