Bryston 7bsst vs 28bsst?

Larry Greenhill in Stereophile stated that by BYPASSING the
rear circuit breaker in the 28,that into 4ohms,she'd do 1800w
continues for 10 to 20 seconds before the 15A BREAKER would trip.
Bryston chose an 8ohm rating because of regulartory agencies
test amplifiers under HOME CONDITIONS and that it would NOT
trip the average home breaker.

What are the capabilities of the 28B at 4 ohms if you don't bypass the rear circuit breaker on the amp? Bryston should state the amp's 4 ohm capabilities without having to bypass anything. That 1800 watts stereophilementions is a peak rating for a very short time. I'd like to know what it will do at 4 ohms for a sustained period. Bryston isn't stating it and I'm suspicicous.

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

I can't run my 28s with my pre past 9:00(I could but she'd
rock the neighbourhood+mine).
A couple of thousand watts,you could fill up a 300-500 seat bar and with plenty of sound to spare.
Now if I ever get a bigger house,WE ARE MORE THAN READY.
I was ready with the 4s+7s let alone these superb 28s.

Shannere, the obsession with ratings is that if you have 4 ohm speakers, you could run them with a 500 watt amp that doubles down into 4 ohms without worrying about circuit breaker problems. The whole point is moot if you're running 8 ohm speakers. If you've got 4 ohm speakers, someone had better answer some questions and document it. I have a set of Infinity Kappa 9's that dip to 1 ohm and below. I'd certainly like to know if the amp has the testicular fortitude to handle those low impedances for sustained periods without bypassing the circuit breaker on the rear of the amp or worrying about tripping the house circuit breaker. I'm sure someone that owns a set of low impedance amp-killing Apogees would certainly question this amp's performance at 4 ohms and below. Krell lists its amp at 900 wpc @ 8 ohms and 1800 wpc rms @ 4 ohms.

Sorry, but when putting out that kind of scratch, I'd like to see its 4 ohm performance in writing.

The 7B SST states that it will go to 900 wpc @ 4 ohms. Something tells me that the 28B SST won't perform any better at 4 ohms. So, if you've got a 4 ohm speaker, you could probably save yourself some dough and go with the 7B and be assured of your 4 ohm performance. I still see question marks all over the place for the 28B.
