Did do a search but couldn't seem to find an answer. What I would like to ask is, Is it safe to wire 2 amps to one set of speakers?. I am interested in purchasing the Cambridge Audio 640A. At the moment I have the CDP going through the Marantz amp, and the stereo output is not that hot. I am hoping that buying a seperate amp would improve the quality of output. So any help would be greatly appreciated.
