HagUSB vs Other USB Interfaces/Devices


Hi all. I have three quick questions regarding the HagUSB:
1. how does it compare to other USB interfaces, in particular those with true ASIO support (Edirol, M-Audio etc.)
2. does it provide bit perfect output (i.e. does ASIO4ALL provide bit-perfect output even though it still uses the OS)?
3. I currently have an Edirol UA-1EX which I used as both an interface and DAC (used it analog outs). I now got myself a DAC which has both optical and coax input. The Edirol is going to another PC so I want to get either one of those interfaces like the M-Audio Audiophile USB, but have read that the HagUSB is superior (even though it does not use true ASIO and only supports 16-bit). Is it a good "upgrade" to the UA-1EX?

Cheers,

Does this mean that even a next generation DAC which comes with a USB input will receive corrupted data unless one also tinkers with the Windows operating system and drivers?
xenithon,
sorry to ventrue off topic. but i am wondering how the edirol UA-1EX sounds. i have heard good things about the previous edirol UA-25 but am curious about the UA-1EX. i am looking for a cheap interface that sounds pretty good to hook up to my external dac. have you used the UA-1EX without the D/A function?
thanks

Hi there,

Sorry for not replying earlier....have lost touch with this thread :)

Yes indeed I have, and still do. I now use the Edirol as a pure USB interface, so that I can pass a bit-perfect signal using ASIO out to an external DAC. It is now exceedingly better than before (using a Musiland MD10 DAC, fed by digital optical output from the Edirol).
