Black Ice F-22 vs CJ CAV45 S2?

I am currently on the lookout for a CJ CAV45 S2 integrated after hearing the original CAV 45. Has anyone had a chance to compare a Black Ice F-22 with either of the CJ integrated amps? Based on a number of comments and a solid review, I'm wondering if the Black Ice is in the same league. 

Any comments based on real experience with either/both are appreciated.

Thanks for looking!
