I just picked up a really nice SX-1280. Everyone speaks so highly of the sound, I just had to compare it to my SX-1980. Well, the verdict is in and the SX-1980 is better, no question. They are both very nice, but the 1980 has a slightly richer, fuller, tube like sound. Very close, but not the same. The SX-1980 also has a better look IMHO and the tuner is better too. I love them both, but the SX-1980 is the king of receivers for a reason.
