I got my 898's before they offered the interpreted DI. In other words, I Didn't buy them for DI. Then, they offered the update with DI and I was like Brett and at first didn't get great images. I figured it was due to not being a dedicated crystal. Some local buddies and Kosmo's posts showed that you could dial them in. I went back to playing with it and started getting good images.

I believe having confidence in your stuff is a necessity. The other is not to be afraid to "mash" them buttons.

But I am an engineer and realist. A dedicated crystal for DI is going to get you the best results for that application.
