Comment on Harmon 'trickle' tech... The previous owners of Levinson left over disagreements about Harmon sticking a crap rebadged Harmon amp (that skinny one channel thing that used to be a Marantz junkheap) into the Levinson line.
So it is the OPPOSITE effect. Harman is watering down the Levinson brand, to sell crap to brand suckers. The prior owners/advisors quit to protest the distruction of a once famous brand.
Also, I read all eight pages of the Canuck posts. The pro/con for Bryston was pretty even. With little complaint about newer Bryston amps, and the naysayers all were dissing older Bryston amps, or saying they preferred another brand (which they seem to prefer as being more 'musical'...ie:pleasantly colored sounding.
The discussion about quality, or price performance was equally interesting. The discussion about why so many, well they do last a long time, and folks who own them buy new ones, and the used buy and sell. So it makes sense as why so many are out there for sale (especially IN Canada!!)
Another point to make is that Bryston uses the same system for the amps. So a very old model beginning with 4 and the evolution into 4B 4BST.. 4B-SST2 so when one reads about an amp, it can be a variety of model with nearly the same designation. Most amp makers change the model name system enough to make a break with older models. Or, the company folds, or is bought by another company..
