I got a refurbed Onkyo 805 for $600. Runs warm, too warm. Popping while skipping tracks has happened on two movies, out of about a dozen. Big 51 lbs, needs plenty of ventilation. 60 amps as opposed to 36 amps of 705/605, Ultra2, MultiEQXT, preouts, Burrbrowns, can matrix 5.1 hi-def sources into 7.1. The 605 def cannot.
