Kal and Eldartford : thanks; I was looking at the Behringer. I am not necessarily addressing a particular problem, Rather, my interests are in objectively evaluating the response of my system and correcting, if indicated, any deficiencies. What I am looking for is an efficient way of inputting a signal of known frequency content and measureing the response at a point in the room. Then inserting the filtering and seeing if I like the result. One box that does both of the above is what I am after. System consists of Marantz CDP - Mcintosh C45 preamp - Mcintosh MC 402 amp - B&W 803S speakers.
