if you compare the simulated topology with the circuit in the JAES paper, you will notice that the current dumper (complimentory pair) is actually the "main amp", and the opamp is the anxillary amplifier, whose job is to correct the (cross-over) distortion in the dumper.
yes. most (Linn 3-stage) amps have an input stage + voltage amplification stage, which drive an output stage (complimentary pair). As such, you can easily reconfigure the first two stages as the anxillary amp, and the output stage as the current dumper.
