With peaks well into the 540 Watt max on the power meters! A rare beast that is sought after by many audiophiles who would give up anything to get one!

Nothing has ever been built like it, and it never will be built again. this photo is from the thread "Pioneer SX-850 Score" in the AudioReview Forums.
