Excellent Condition Perfect Working Order Includes Power Cable

What we have for sale is theProceed Power Amplifier AMP2 These are the first generation of the Proceed ampsthat were a joint venture of Mark Levinson Labs and Madrigal Sound. These were hooked up to a Classe SSP-600Preamplifier Control Unit. This unit is in good operating condition with noproblems or shorts. This just does not get used enough to justify keeping.Besides that I have gone to a single receiver forsurround sound duty: and I have too many stereo set ups for music so these just are not used much and they need a good home. Would be good in a two channel set up. Please look at the photos carefully for an idea of condition. Please ask if you have any questions or need more photos. Ships Fully Insured with Signature required. UPS shipping is no longer offered due to issues with delivery by that service provider.

Manufacturer Description: This Proceed (Mark Levinson/Madrigal Audio Laboratories) Amplifier is a triple monaural design with three separate power amplifiers, one for each channel. It outputs 125 watts per channel into 8 ohms, and doubles to 250 watts into 4 ohms. It has the power you need to drive even very difficult loudspeakers. It is stable into 2 ohm loads. The amp is completely mono-block in architecture, with individual Plitron toroidal transformers, and power supplies with 42,000 microfarads of capacitance for each channel. The build quality is superb. The result is a very heavy amp (approx. 70 lbs.). My Description: This Proceed Amp is in excellent working condition as well as visual condition. There are no scratches on it. The unit was used from the time we purchased it new until Dec 2023 when we remodeled and changed to a different system. We never had any issues with the functionality of it. Please see all photos for all that is included in the offer. It does also include two USB mini cooling fans we used in the cabinet with it.

Proceed (from Mark Levinson) AMP3 Amplifier 3 X 150 w/ch @ 8ohms 3 x 250 w/ch @ 4 ohms 1 x 500 w/ch @ 8 ohms (bridged) 20hz-20khz < 0.1% THD Weight: 80 lbs. Special Design Features (From the Owner's Manual): Multiple monaural design Consistent with the finest amplifiers, your Proceed AMP is a true “multiple monaural” design. Each audio channel has its own, dedicated power supply — including a separate 300VA toroidal transformer for each channel. This approach re- duces crosstalk between audio channels for superior imaging and reproduction of acoustic space. The demands placed on one channel have virtually no effect on the performance of the other channel(s). 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 AMP 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, immediately adjacent to the output transistors (which require the greatest amount of current). The layout of the circuitry uses short, thick traces for high current paths. Internal current capability is further enhanced with high purity copper buss bars. This attention to detail yields an optimal environment in which the amplifier may operate to its maximum potential. Balanced inputs Each channel of your AMP 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 AMP adjusts automatically when you select different inputs to facilitate this “mix and match” approach. Robust output stage Each channel of your Proceed AMP uses eight 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 DC (direct current) at the output or an unsafe operating temperature. In either 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 excessive current conditions such as driving shorted outputs. Finally, inrush limit- ing prevents premature aging of power supply components during power-up, and switches off-line once the power supply has been charged. Home THX Audio System certification Lucasfilm, Ltd.® has established minimum standards for the performance of various components which may be used in their Home THX® Audio System. With respect to power amplifiers, the standards address such things as: • a low electrical noise floor to allow low-level information to be fully appreciated; • the absence of any mechanical noise (fans noise, transformer winding buzzes), for the same reason; • adequate power to meet the demands of modern films (which can be quite dynamic); • flat frequency response for accurate reproduction of timbre; • stability into relatively extreme loudspeaker loads, to ensure that the amplifier will perform well with a wide range of loudspeakers. As you can see from this list, there is nothing about the Home THX amplifier specification that is particularly radical. It simply ensures a certain minimum standard of performance. In particular, there is nothing in the nature of the amplifier specification which prevents anyone from going above and beyond the minimum performance levels required by THX certification. Both the Proceed AMP 2 and AMP 3 are certified for use in Home THX audio systems. In these products, Madrigal engineers have created powerful, versatile and extraordinarily musical power amplifiers, using the technology and design methodology for which they have become so well known. Equally suited to the rigors of film soundtracks and the finesse of high end music reproduction, the Proceed amplifier serves both needs quite well. In today’s growing market for multi-purpose systems, they represent an extraordinary value.

A bit of an unusual amp here - this is a Proceed Amp 3 with two channels working (Center and Left). Ive been using this a two-channel amp for a year, powering B&W Nautilus 802s, and sounding great. This is a Mark Levinson-designed amp, after all, and sounds fantastic even with difficult loads. If you know this amp, you know that this a bargain for essentially a 2-channel Proceed amp.

I’m looking to finish (for now) my 2 channel set up, so to that end I am willing to trade for the right 2 channel amplifier. Some of the brands I would trade for include, McIntosh, Classe, Krell, Mark Levinson etc. Shipping price will be determined at sale as I have no idea where it’s going yet. The price reflected in shipping is a wild guess to the furthest place from me in the U.S. as such, is not an actual figure. Thank you. This offering of audiophile gear includes a Proceed Pre Preamp, (Sometimes referred to as the Baby Levinson preamp) this unit is a straight 2 channel set up and has NO processing for home theater which could potentially add noise to your system. a Proceed CDP HDCD Player, which shared the same transport and laser assembly as a few of the finest brands available from around the same production time as the Proceed, such as Krell, Levinson etc. and truly sounds amazing), a Sunfire load invariant Stereo Amplifier (300 X 2 @8 ohms, 600X 2 @4 Ohms and 1200 x 1 bridged @ 4 Ohms. It’s even 1 Ohm stable and will NEVER run hot! ). a pair of KEF Q550 speakers in excellent condition with very low play hours, Approx 30 or so and a Sunfire Mark IV True Subwoofer! This is truly a plug and play audiophile system!Proceed, a brand produced by Madrigal labs, makers of Mark Levinson gear is some of the best gear you can lay your hands on at the price point. Both the cd player and the preamp have been in for service, cleaned and realigned and work as they should. All led’s work and there are only minor surface scratches visible in some small areas of the equipment. The universal remote is included and operates both the cd player and pre amp with no issue. The Sunfire Amplifier is a beast,and has balanced inputs, heavy 5way binding posts, RCA inputs and provides plenty of power for almost anything you can throw at it, (see above) also the led on the Sunfire Amp Joule Meter has been replaced and works with no issues. The speakers are in excellent condition and have only very minor flaws, nothing that would affect performance of the drivers or even the aesthetic of the speakers. And for the low end the Sunfire Mark IV True sub rocks the house with 1750 watts of Punch! This type of equipment doesn’t come up for sale often, if ever the preamp is a bit of a unicorn and pretty rare in that it’s straight 2 channel with no processing and is sonically unbeatable with comparable models @ $3000 and under. The cd player, amp, speakers and sub are a killer pairing that begs to be played and heard. Please let me know should you have any questions, thank you for looking.

For example, the power supply capacitors (which act as “reservoirs” of power for the amplifier circuitry) are mounted directly to the printed circuit board, immediately adjacent to the output transistors (which require the greatest amount of current). The layout of the circuitry uses short, thick traces for high current paths. Internal current capability is further enhanced with high purity copper buss bars. This attention to detail yields an optimal environment in which the amplifier may operate to its maximum potential. Balanced inputs Each channel of your AMP 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 AMP adjusts automatically when you select different inputs to facilitate this “mix and match” approach. Robust output stage Each channel of your Proceed AMP uses eight 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 DC (direct current) at the output or an unsafe operating temperature. In either 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 excessive current conditions such as driving shorted outputs. Finally, inrush limit- ing prevents premature aging of power supply components during power-up, and switches off-line once the power supply has been charged. Home THX Audio System certification Lucasfilm, Ltd.® has established minimum standards for the performance of various components which may be used in their Home THX® Audio System. With respect to power amplifiers, the standards address such things as: • a low electrical noise floor to allow low-level information to be fully appreciated; • the absence of any mechanical noise (fans noise, transformer winding buzzes), for the same reason; • adequate power to meet the demands of modern films (which can be quite dynamic); • flat frequency response for accurate reproduction of timbre; • stability into relatively extreme loudspeaker loads, to ensure that the amplifier will perform well with a wide range of loudspeakers. As you can see from this list, there is nothing about the Home THX amplifier specification that is particularly radical. It simply ensures a certain minimum standard of performance. In particular, there is nothing in the nature of the amplifier specification which prevents anyone from going above and beyond the minimum performance levels required by THX certification. Both the Proceed AMP 2 and AMP 3 are certified for use in Home THX audio systems. In these products, Madrigal engineers have created powerful, versatile and extraordinarily musical power amplifiers, using the technology and design methodology for which they have become so well known. Equally suited to the rigors of film soundtracks and the finesse of high end music reproduction, the Proceed amplifier serves both needs quite well. In today’s growing market for multi-purpose systems, they represent an extraordinary value.
