Hardly a Troll. You guys all forget that the point of this is to enjoy music. I have all the things the OP asked about. If he wants the best musical experience, the C700 will romp on the wiim ultra in every way. It's just that simple. Buy both and A/b them and measurements aside, I'm pretty sure every single one of you would prefer the C700. Yes it's a little more, but It gives a far more enjoyable experience. You guys sound just off. I've owned maybe 10 dacs, obsess over finding the best bang for buck items that bring about the highest level of music satisfaction . Your measurements are only part of the equation. I have an interior design business and sell speaker systems to some of the biggest music producers in the world. I don't sell to audiophile types for the reasons above. You guys are so full of yourselves when real world sound and experience is what ultimately matters.
