Onkyo M-510 Power Amplifier with a fresh restoration: Ultra rare, ultra heavy, and ultra beautiful tubes All the logic controls andAs rare as it is heavy (insanely), the Onkyo M 510 is a power amp from the golden era of HiFi audio equipment. 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.
