Unsound,
You can also check out the reviews by Stereophile, such as
Martin Collums April 1997 review of the then current FPB-600.

In the Measurements segment, Martin addresses the power that
the amp can deliver into low impedances:

"I wasn't able to run my long-term continuous testing at
2 ohms, but compromised with five-second bursts-long by
peak-measurement practice (eg, 20ms). The FPB 600 could
sustain a 29.3dBW level into this load, corresponding to
3.4kWpc-an extraordinary figure."
