What you really need is a power meter on the amp outputs. I think you can find them on ebay.

How to measure the preamp output?
Can someone please tell me how to measure the output of a preamp. I am feeding the output of a Bryston BP-25 to a First Watt F5 and I'd like to know just how much voltage I am feeding to the amp in order to ovoid driving the amp beyond a safe point. I am using the First Watt F5 to drive a pair of Opera Quintas (89 db sensitivity) in a small room (10 x 16 ft). Any help would be very much appreciated!
