I am considering an Onkyo PA-MC5500 amp for my Integra DHC-80.3 because my old B&K power amp has a dead channel. The Onkyo has the same specs as the Integra DTA-70.1 amp but is cheaper. I can't seem to find anywhere to buy the IRK-180-4 rack mount kit. None of the authorized online dealers that carry the Onkyo have the rack mount when I do a search. Any ideas?
