From reading the description, it sounds a lot like what Herbie's grungebuster mat did for me. The gel probably has a lot to do with that...
I listened to the previous version of Auric Illuminator on a very resolving, perfectly setup system and heard a very little difference than without. So, I would hope the new version would be better.
Based on my limited knowledge, I'd say the added weight and dampening properties of the gel is the biggest helper.
