I have an older Harman Kardon AVR-520, which is a tank. I wonder if I should consider upgrading to this?
Granted, the HK is *old* but it works great and sounds great. True, it doesn't have many of the newer features and no HDMI at all. But I'm using digital cables for sound and then going directly from the source to the HDTV for video.
HK receivers have a great high current design, as you may know, and handle difficult loads very well. They tend to be conservatively rated too.
What do you think? Stick with the 520, which works well, or upgrade to this?
