"Bridging is the process of using the output of one side of the amp to drive the inverting input (feedback point) of the other side of the amp, in a typical Lin-topology amp. This is technically "in series" and can have sonic consequences that are not ideal.
Vidar is not a Lin topology. When used as a monoblock, it is simply amplifying a differential signal. It is not bridged."
Something to keep in mind regarding the Vidar Amplifiers.
