hmmm. I may try it. I have been happier with my Hd500/Dt50 than with anything else I've tried. Using the hd500 direct or with the amp, there are no latency issues, and I have been able to find tones I like. Guitar rig, amplitube, scuffham...haven't really done much for me. I know I'm in the minority on Scuffham, but even at 7ms of latency I found it pretty annoying. Maybe with Sonar X2's improved audio engine these things will work better.
