When I was upgrading my amps, I did ask the Paradigm/Anthem rep if I should go with an Anthem amp or a Bryston amp to power my Studio-100. I didn,t believed it, because he did told me to buy the Bryston 4BSST! That,s customer services! Pushing a competitor product.
But Anthem, Rotel and Parasound are all making good amps to go with the Paradigm. If you have the money, a Bryston amp is tough to beat, with 20 years transferable warranty. And the sound is spectacular.
I,m using a Bryston 4BSST and a Rotel RMB-1095 with my Paradigms. But I would be hard press to hear a difference between the Rotel, an Anthem or a Parasound amp.
