Budrew -- I have the Wavelength Cosecant (after trading up from the Brick), and have to second Terrat's observations. Both are the best digital I've ever heard, and while the Cosecant is significantly better than the Brick, I'd have to say the latter is more of a bargain. (Both are basically the same USB DAC design, but the Cosecant has an output transformer and a better power supply).
I have no experience with other USB DAC's. I'm fairly sure that a lot depends on how well the USB controller is implemented and how good the actual DAC part is. For example, Gordon Rankin uses no up or oversampling. I don't say this because it is necessarily better or worse, just to indicate that different USB DAC's are likely to sound different, like everywhere else in audio. Make sure you buy something that sounds good to you in reality, not just in concept. End of lecture ;<) Hope that helps. -- David
