Boom of death!!
My Cambridge audio 740a has started to make a very loud boom/thudd noise through the speakers quite often when it is powered up. This seems to trip my amp and the readout says possible internal amplifyer failure. I sent it off to Cambridge audio and they did a factory reset and ran it for a couple of days and said there was no problem. it came back home and seemed okay for a couple of days but it has started again. Anyone have any ideas what it might be? I am planing to send it back to Cambridge audio but I am worried it may be something else in my system causing it or they will just tell me it is fine.
Any ideas would be great.
