Onkyo spared no expense when they created their flagship amplifier. The physical build quality is second to none and the electrical design is complex, interesting, and robust. Did I mention its heavy? This massive beast weighs about 150lbs. Onkyo sold a limited number of these puppies in the United States and very few are left in circulation.
