I’d second emotive’s suggestion that Echoaudio’s drivers are stable, until recently I had used Echo Laylas for years and never had any issues on a number of PCs. Their hardware is relatively inexpensive and has always been rock solid. I upgraded my PC last year and got one put together by Arbico computers ( http://www.arbico.co.uk/ )who did a great job, and their customer communication keeping in touch via email with build progress etc was great… good value too I thought.
