I ultimately came to the same conclusion. When I compared it to an L-2500, the Dimension came across as very refined, almost 'dignified' in tone. The L-2500 was more of a a snarling beast. When compared to my ACG Uber custom, it lacks the depth and clarity of that bass. (The Uber is a pretty good example of type of sound you get from high-end boutique instruments.) I wouldn't be surprised that a small improvement in the pre-amp would correct these issues.
