I just purchased a couple MA-500 monoblocks to power the fronts. They're connected to the pre-outs of an Onkyo NR717. I use a Logitech Harmony 650. Can the Marantz be controlled by an infrared remote? I selected MA500 in the Logitech software and it doesn't do anything. I just want to be able to put the MA500s in standby when I turn off my system. They have RC-5 connections but I'm not sure if that's helpful without a Marantz preamp. Thanks in advance!
