Sx1980 tons o problems. Frying the boards due to improper engineering. The 1250 is a much better receiver and the very best one pioneer ever made. I’d still take a sansui g9000, 22000 or the mother of all receivers the 33000 over any of them. The old receivers are really cool and nostalgic but have a very bloated sound compared to today’s equipment imo. High Wpc doesn’t equal better sound.
