Bryston 4B-ST overkill for Paradigm ??

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.

We all have to draw our own line in the sand somewhere... If you do not perceive the Bryston to be worth 3X as much then it will not be a good buy in your eyes. Purchasing the 4BST will no doubt alleviate any amp "upgraditis" you might get with the Anthem (which btw is a nice product but is not a Bryston amp). Its too bad that you can't try out both as only your ears will define how much $$$ you are willing to part with. Remember that when you get past "low-fi" on the way to hi-fi the costs go up exponentially... Slight or incremental returns for what can be large investments!

I agree that trying both out in my home with my gear would be the optimum, but it is not possible. I don't mind spending the money for the Bryston if it is worth it, I don't think it will be 3 times as better than the Anthem but I would be willing to pay a premium for an overall increase in performance. Keep the suggestions coming, thanks.
