I have no experience with the other CA models, only compared with the DR8. The heatsink metallurgy between these two amps sounded very different. The CA300 had the upper hand in deep bass response but the DR8 was superior from the mid band up. With the heatsinks damped, I then preferred the CA300 although the DR8 was still superior on voices.
Experiment and report your findings. I'm curious to hear your impressions.
