Bryston 7bsst vs 28bsst?

Bryston does not list the 28B-SST output at 4 ohms. I wonder why?? For an amp that boasts 1,000 wpc @ 8 ohms, omitting the output at 4 ohms is a glaring omission and immediately sends up a red flag in my book. The 28B-SSt is two bridged monoblocs. Bryston does list the output of the 7B-SST at 4 ohms. My guess is that the 28 might have trouble with a 4 ohm load. I suggest you call Bryston before you pull the trigger on a 28B-SST and ask them how the amp will perform at 4 ohms.

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.

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.
