i think the t3000 vs the collossus 2 would be a better comparison in terms of power. In terms of built quality i would take the t2000 as i have been hearing too many problems with the higher end hifonics amps.
The RF Power amps are under rated big time, my t30001bd has been running real strong. It's powered a 18" Fully Loaded BTL without a sweat and will soon power (2) RE MT 18's.
