Bryston 28B SST

.
How does the 28B SST stand up to low impedances?? Bryston clearly lists the power output of the 7B SST at 4 ohms. But, it is a glaring omission when it fails to mention the 4 ohm rating for the 28B SST. Bryston mentions that the 28B SST is a bridged design. To me that is a red flag to be wary of its performance at low impedances. I have a set of Infinity Kappa 9's that dip to one ohm, I'd like to see the 28B SST take a stab at them.

The review in the link below from a review in stereophile magazine addresses the low impedance issue. The review may answer the questions why some users above thought the 28B SST was lacking in dynamics. If you have speakers that go to 4 ohms or below, the 28B SST may not be a good match.

The 'Sqared' design is still two bridged amps. For Bryston to omit the power ratings into 4 ohms and 2 ohms is a glaring omission. Speakers that dip to two ohms and below would choke the life out of this amp as it's configured on the website. Bryston doesn't even bother to mention the availability of a paralell configuration on the website. The paralell configuration would probably manage 4 and 2 ohms quite well, but then, Bryston couldn't make its lofty boast as a 1000 watt amp into 8 ohms.

Very misleading by Bryston to do this. As its flagship amp and at $16,000 per pair, I think full disclosure should be paramount.

Krell posts its power ratings form 8 ohms all the way down to 1 ohm. Parasound posts its ratings from 8 ohms down to 2 ohms.

To Bryston's credit, they do post the 4 ohm ratings for every other amp except the 28B SST.
