Correct me if i'm wrong but isn't that amp 50 watts of pure class A, if it is I wouldn't use it for the woofers, the woofers are crossed over so low with a steep slope that you don't hear any vocals at all out of the woofers, in fact all you hear is the bass, I tried these amps for my woofers, a forte 3, 200 watts, an adcom 555, 200 watts and adcom 585 250 watts on my woofers, the guy I bought my epsilons from was using a bryston don't remember the model # on the woofers, I use a forte model 4a 50 watts pure class A for the high frequency drivers.
