The remote for my Audio Research LS-17 stopped working. I purchased a Harmony 650 remote control ($49). It requires a simple online setup that recognized the ARC model. I just tested and volume/on/mute are working. The other couple of functions probably work but I haven't invested any time in figuring out the buttons for those. I suspect even the cheapest Harmony remote will work with ARC products. I didn't test any other model.
