Yep, if you look very carefully you can see the 4500's transformer is slighty larger, followed by the 6014 at the bottom, 7013' s transformer would be identical in size to the 4500's, likely exactly the same except look different on the outside.Peng, I didn't think it would be fair to take a guess since I already knew the 3600. it's the middle one.
Top one looks like the avr -x4500h (maybe)
Bottom one looks like Marantz SR7013![]()
