In the Enjoy the Music review they sum with:

"In my review of the Equi=Core 1800, I stated that the effect it had was magical resulting in quieter backgrounds and a deeper three dimensional image. I really did not think it was possible to squeeze much more improvement out of the system until I inserted the Deep Core 1800 and then properly adjusted it. The improvement top to bottom was similar to the effect that occurs when you clean a camera lens. Everything snapped into clearer focus. The soundstage deepened with images locked solidly in place. I honestly didn't think it would make this much difference, but it did. Okay Walter, let me sum it up like this: You can't have the Deep Core back either."
