I have the 28S mated to a pair of Verity Audio Parsifal Ovations. I selected these amps after looking into several others, the final two contenders were the Clayton M300 and the Brystons. The POs just sounded better with the Bryston, but the Claytons were very good.
Its my understanding that the most significant difference between the 28s and the other SST models (other than power) was the transformer (layout, etc - I am not technically proficient). However, when the range went to the "2" designation the same transformer "system" was then used in all the SST products. At which time the performance gap between the 28s and the 14B/7B -SST closed.
I had reviewed the 4BSST which was outclassed by the 28-SST2, but, again, that was before the "2" revision.
All and all, the 28s are a SOTA solid state neutral amp with tons of overhead. You should give them a listen....
