I am on the fence as to which poweramp to choose. I really like the CA9 sound that everyone talks about, but I also like the weight of the st2000. I play a 5 string custom spector that is VERY hot, and I haven't found a setup that can handle my low B string yet. I have a sansamp RBI preamp, and a schroeder 410r cab rated at 1400watts rms at 4 ohms, all I need now is a poweramp. It's either gonna be a crest CA9, LT2000, or a ST2000. I would love some input as to the st2000. Has anyone A/B'd the CA9 and the ST2000? Any input would be appreciated.
