My MRX 700 made an exploding noise through the speakers and shut itself down - twice. Worked fine right after but next day, the main left speaker out is nothing but loud static regardless of input or volume. I swapped the cables and outputs and it is definitely the main left speaker output. I called anthem and it costs $130 just to take a look, plus parts but they will toss in small parts if that is all it takes. Tech is guessing it is a minor repair but one never knows. Probably about a 3-5 week wait for repairs after dropping off. Question is - is it worth going direct to Anthem (I am within a short drive) or any downside going to a well reputed local guy to check it out and possibly repair. I would expect anthem would use all oem parts and offer a warranty on repair, no idea on the local guy. Thanks for your insights.
