Jim Tanner of Bryston has stated that the 28B run full power into 4 ohms will trip the circuit breakers in your home panel and they would have problems with Underwriters Labs if this figure were published. Going by the ratings of other Bryston amps usually the 4 ohm rating is about 1.7 times the 8 ohm rating.
Why the obsession about the ratings even if it did not put anymore into 4 than 8 when do you need more than a kilowatt per channel anyway
