Here are five that come to mind. Have heard all of these at RMAF at two different shows (2009 and 2011) and, in the case of the YG Anat, also at GTT Audio last December.
Given the enormous price difference between these models and the CLX, it further underscores the incredible value of the CLX from a performance / cost perspective. Please note that all of these are "full range" and don't need a sub(s) to augment the low end. But even with a couple of subs, the price difference is still extreme.
1) YG Acoustics Anat Pro.
2) YG Acoustics Kipod Sinature II.
3) MBL 101E.
4) Focal Grand Utopia EM.
5) Focal Stella Utopia EM.
To optimize performance, the usual caveats apply to these and the CLX's. Proper set up and proper equipment.
PS: To repeat a previous post, I interpret the word transparency to mean that the speaker gets totally out of the way and allows one to become emotionally connected with the music on all levels.
