Finding it hard to fathom the ruggedly built CA-200's not being able to handle the Thiels. Granted, the Thiels are a fairly tough load but gotta think that something is wrong with the amp. Perhaps, the bias has drifted and needs to be adjusted. Is there an AC issue? Are both amp and preamp DC-coupled?
Anyway, bridging not advisable as that doesn't increase current into low impedance loads and just as likely to make problem worse. The increase in power from bridging is mostly voltage which only helps you keep the volume knob a bit further back.
