"Summing up
At $16,000/pair, the Bryston 28B-SST is a serious investment for any audiophile. But for those with large listening rooms and speakers of low voltage sensitivity and 6–8 ohms impedance, the Bryston's price and 1000W power rating compare well with those of other high-end, solid-state monoblocks. It combines the top-end delicacy and sweetness of my Mark Levinson ML-2 class-A solid-state amplifier with the raw bassmaster capabilities of a Bryston 4B-SST or 14B-SST. In many ways—high power output, monoblock flexibility, basically wireless construction, reliability, stability, and 20-year warranty—the 28B-SST is one of the most outstanding amplifiers at any price. Come to think of it, the 28B-SST is just the right amplifier to capture the raw power, passion, sonorities, and subtle inner details of Golijov's Azul, should a recording of the work ever be released. I can't wait." -- Larry Greenhill
"The amplifier comfortably exceeded its 1000W/30dBW specification into 8 ohms, delivering no less than 1300W (31.15dBW) at 1% THD+N. (The wall AC voltage dropped from 125.1V to 120V at this power level.) Into 4 ohms, the Bryston clipped at 1800W (29.5dBW, 117.5V wall voltage), though it couldn't maintain its high power into 2 ohms, delivering 1050W (24.2dBW, 116V wall voltage).
...
While it definitely works better with speakers having impedances of 4 ohms or greater, Bryston's 28B-SST joins that select group of very-high-powered amplifiers that have sufficiently low noise and distortion to reproduce high-resolution digital recordings without compromise." -- John Atkinson
