For one, most USB DACs, including some $2000+ ones, are limited to 16/48 by a previous technical limitation. So calling it bad just because of that is ignorant. It doesn't have a specialized driver.
The M-Audio Transit is actually a poorly reviewed device, if I recall. So you being high and mighty about it is kind of funny.
Also, the uDAC has a unique pricepoint, and is well reviewed, even against some products over twice the price. It runs a fairly high quality ESS ES9022 DAC chip.
I was referring to the specs as means to compare a device with typical usb1.1 specs vs one going above it. I was not praising the Transit for its amazingness, it just wasn't actually horrible. (You can find reviews going either way, it does a great job as transport, sounds better than a PCM2702 based dac, but it doesn't sound as musical as the DAC attached to it, not the point at all though.)
The 16/32-48 sounds like they come from the usb receiver then anyways if the actual dac is the ES9022.
I was commenting on the posts saying it needed a special driver, when the specs seem to suggest it should have a receiver chip that shouldn't need any special driver as it's in USB Audio 1.1 range (think of the myriad of USB dacs with PCM270x or PCM290x receivers alone, not counting the CS, CM or others out there), and if nuforce did something to need one, that's then junk. (Read it as the attitude of manufacturers, not the quality of the device (at its pricepoint))
And if it does not have/need a specialized driver like you say, then there is just more FUD in this thread that's junk.
