Used 3 Channels Power Amplifier from Madrigal (Mark Levinson) 500 Watts

Very well known brand made by Madrigal (Mark Levinson) in US.

500 watts 3-channel power amplifier.

Natural sounding amp resulting in superb detail and clarity for both music and movie use.

Movies dialogue is so clear and crisp with this amp use.

The unit operates 100% as intended and sounds fantastic.

Super heavy around 45 to 50kg. Solid built unit.

This amp is maintained well in air-conditioned areas with no smoking and no pets too. Please check Google reviews and info to learn more about these limited units of great amps in M'sia.

I use one of these for LCR speakers in a 7.1 configuration of Bohlender Graebner ribbon speakers which are a resistive 4 ohm load. The BPA's are a perfect match as they provide a huge power reserve (500 watts per channel).

Proceed HPA3 Amplifier, 3 Channel Monaural Power Amplifier, 3-Channels. 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.


Triple monaural design
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 trans- former 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.

Low impedance power supply
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 au- dio 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 printed circuit 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.

Balanced inputs
Each channel of your amplifier is individually configurable to receive either balanced or single-ended inputs. This approach allows you to take full advantage of the greater immunity from noise, RFI, and EMI which balanced transmission of audio signals offers on any preamp-to-amplifier connection where it is supported. At the same time, any or all channels of the amplifier may be configured for single-ended inputs to maintain compatibility with the majority of preamplifiers available today. The gain structure of the amplifier adjusts automatically when you select different inputs to facilitate this “mix and match” approach.

Robust output stage
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.

Extensive protection
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 disconnected from 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.


Selling for RM9500. Still a little negotiable for serious buyers and welcome to test.

The original retail price is around RM25k++

Condition: 8/10 due to no box, anyhow the amp is in great condition.
