Condition is unknown, so the US$450 ask sits as a strong deal against your comp set: it’s below the US$450 25th percentile only if you treat that floor as the edge, and well under the US$650 median and US$875 75th percentile. For a buyer, that makes it a very buyable number rather than a stretch.
This line has a solid reputation as a musical, straightforward analog preamp with the sort of build and sonics that still pull interest from vintage-hifi folks. At this price, the upside is real if it’s clean, fully functional, and complete with remote or original packaging; the main buyer watchouts are age-related service needs and any channel-balance, switching, or noise issues that would eat into the value.
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.
