I compared the Pass X-250 to the Edge 10. The Edge was faster, slightly more dynamic and a bit clearer sounding. But on some recording, I felt the Pass was more accurate to the instruments, and held notes a little longer which again depended on the recording as to which one I liked better. I ended up with the Pass mostly because of the price difference $6K versus $10K for what may have turned out to be a slight improvement. The extra money helped me to buy a really good preamp.
Happy Listening.
