First, think twice about dealing with a business which won't allow you at least a satisfaction guarantee. The Bryston is close to state of the art in design and has a 20 year warranty. However, most modern solid state amps are durable and sonically acceptable assuming that they have sufficient power and headroom for your application. If cost is a strong factor in your decision, try the Anthem with a reasonable return option. Otherwise, my preference would be for the Bryston.
Bryston 4B-ST overkill for Paradigm ??
I have a pair of Paradigm Ref Studio 100s v2 speakers and have been looking for a decent amp to drive them. The Anthem MCA-2 and Bryston 4B-ST are readily available where I live but not for home audition. I can get the Anthem for a good deal, the Bryston is 3 times the cost of the Anthem, is there really that much of a difference between these two amps driving the paradigms, thanks for the help.
