Been using mine for 2 years; great card. I bought mine because it was highly rated by "Sound-on-Sound" mag article. There is also high marks from the Rightmark audio analyzer test (along with some other soundcards tested) here: http://audio.rightmark.org/results.shtml
Just make sure your motherboard is supported and has no known issues - there is a list on Echo's website. The 2 Daws I've had mine in were both pure Intel and I have had zero problems.
