I haven't heard the Premier 12s, but did own the Premier 140 and now own the CA-160s. I would say the Canary amps are better in every regard than the CJ. The Canary amps are well suited for a passive device, while the CJs will probably fare better with an active pre. I am using a Sonic Euphoria PLC with the CA-160s and this is a wonderful match.
