The Proceed AMP 2 has an excellent reputation as a robust, dual-mono Madrigal design with clean, powerful output and unusually strong build quality for its era. At US$400, this is a genuine bargain: it sits well below the US$575 25th-percentile comparable, against a US$750 median and US$873 75th percentile.
Its 150 watts per channel into 8 ohms, substantial power supplies, balanced inputs, and solid protection circuitry make it a particularly appealing match for demanding speakers. The main practical consideration is the listing’s unknown condition: confirm that both channels work cleanly, the unit is set for your mains voltage, and that there is no excessive hum, overheating, or relay trouble. Even allowing for a possible service check, the price leaves considerable room before this stops looking like an excellent buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Proceed
Proceed was established in 1989 by Madrigal Audio Laboratories as a companion brand to the prestigious Mark Levinson line. Founded by Sanford Berlin, who acquired Mark Levinson in 1984, Madrigal created Proceed as a vehicle for introducing cutting-edge high-end audio technologies at a relatively more accessible price point. The brand operated under the Harman International umbrella and was headquartered in Middletown, Connecticut, drawing on decades of expertise in esoteric audio design and engineering.
Proceed built its reputation across multiple product categories, including CD players, digital transports, DACs, surround-sound processors, and power amplifiers. Early Proceed products—such as the PCD CD player, PDT transport, and PDP DAC—featured distinctive upright industrial design and high-quality component selection. The brand later expanded into multichannel amplification and AV processors, including the acclaimed AVP2+6, CVP2, HPA2, and HPA3 models, which became some of the company's most successful offerings.
Positioned firmly in the high-end audio market, Proceed earned respect among serious audiophiles for build quality, sonic performance, and innovative circuit design. The brand was discontinued in 2003, with its best-performing products subsequently rebranded under the Mark Levinson name. Today, Proceed equipment remains sought after in the vintage and used high-end market, valued for its natural, non-fatiguing sound character and robust engineering that has proven durable across decades.
