I had a Marantz once. Probably 10 years ago. The most horrific customer experience I've had with any electronic device. Refuse to ever buy Marantz again because of that experience. Didn't even bother to look and see what they have.
My Onk's HDMI board was pooched from the get-go. I stuck it in my oven for 20 minutes to reflow the cold solder joints and 6 years later it is still working flawlessly.
