Thanks for the responses. I plugged the MX114 in and one of the internal pieces started to smoke. I'm not sure what you mean by "sources" but I work in Pittsburgh. As far as commitment, I'm committed to using the working pieces, but I'm afraid it's going to cost too much to get the 114 fixed. So, I would replace it with a less elite pre-amp if it wouldn't detract from the other components. Does that make any sense?
