MADRIGAL AUDIO PROCEED HPA3 Amplifier It is in excellent condition with No Scrapes, No Dents, No ScratchesRated power output: 250 w/ch rms @ 8W, all channels driven, 20 Hz–20 kHz with no more than 0.1% THD 500 w/ch into 4W I bought this amplifier from George Meyer AV Service Center 18 months ago and they performed a thorough inspection before selling it to me.It has served me well but I made changes to my Home Theater and it is not being used now.It is built like a tank and weighs 100 LBS This Amplifier will provide plenty of power for your front soundstage as it has plenty of headroom.Includes Original Box & Power Cord Will Be Shipped Double Boxed & Insured For Safe Arrival If the DC trigger input is used to control the amplifier(s), thelast mini-jack in the chain must be filled with a dummy 1?8plug [that is, an empty plug must be inserted into the final 1?8[3.5 mm] jack]. Please Note: Even if only a single amplifier is controlled inthis fashion, the “extra” mini-jack must be filled with a dummyplug. There are two recommended methods for connecting speaker cables to the amplifier. A high-quality spade lug or hook lug, soldered to the cable (orcrimped with extremely high pressure), is best. Please Note: Banana Plugs Cannot Be Used With This Amplifier Special Design Features Consistent with the finest amplifiers, each audio channel of your Proceed HPA 3 has its own, dedicated power supply—including a separate 663 VA toroidal transformer for each channel. The resulting reduction in crosstalk between audio channels provides superior imaging and reproduction of acoustic space. Demands placed on one channel have virtually no effect on the performance of the other channel. A critical factor in the ultimate performance of an amplifier is its “power supply impedance,” which can be loosely thought of as the freedom with which the audio circuitry has access to the power it needs, when it needs it.The design of your Proceed amplifier has addressed this important characteristic in a comprehensive fashion. For example, the power supply capacitors (which act as “reservoirs”of power for the amplifier circuitry) are mounted directly to the printedcircuit board rather than using point to point wiring. The layout of the circuitry uses short, thick traces for high current paths. This attention to detail yields an optimal environment in which the amplifier may operate to its maximum potential. Each channel of your Proceed amplifier uses twelve 150 watt power transistors. These transistors are all individually tested and sorted, and are used in matched sets to ensure that no one transistor bears a disproportionate part of the overall load. The combination of an “overbuilt” design specification and extraordinary attention to detail in manufacturing improves performance, reliability, and longevity. Your Proceed amplifier will shut itself down if it senses either the presence of either DC (direct current) or a short circuit at the output, or any unsafe operating temperature. In any case, a power relay will cause the amplifier to be disconnectedfrom the AC mains. In addition, the AC input to each transformer is fused to protect against any possibility of component-level failure that could draw dangerous amounts of power. Finally, inrush limiting prevents premature aging of power supply components during power-up. Once the power supply has been charged, this in-rush limiting circuitry effectively defeats itself to allow unfettered power supply access to the AC mains.

Original manufacturers selling price was $4750. At that time, Proceed, by Mark Levinson, was one of the leading companies in the industry offering all kinds of fantastic HIFI pieces. The HPA3 will pump out a massive 250W per channel into an 8 ohm speaker and into a 4 ohm speaker, a dizzying 500W per channel. Spade connectors included.TESTED - all channels sound great!! The amp is HEAVY (115#) so shipping is going to be expensive. Local pick up can also be arranged.
