Proceed was an American high-fidelity audio equipment brand founded in 1989 as a subsidiary of Madrigal Audio Laboratories, conceived as a more accessible companion brand to Mark Levinson by founder Sanford Berlin. Based in the United States, Proceed specialized in pioneering digital audio technologies including CD players, digital processors, multichannel amplifiers, and audio/video preamplifiers, serving as a testing ground for new technologies before they appeared in higher-end Mark Levinson products. The company's product lineup included the acclaimed PCD CD player family, PDT transports, PDP DACs, and PAV audio/video processors, incorporating advanced Burr-Brown PCM-58P 18-bit 8x-oversampling DACs and sophisticated multi-stage power supply systems. Proceed represented some of the earliest ultra-high-end digital processors and surround-sound decoders in the industry, combining innovative engineering with more accessible pricing for serious audiophiles. The brand was discontinued in 2003 when Madrigal decided to consolidate its product lines under the Mark Levinson brand name, with successful Proceed products like the AVP2+6 and HPA series being redesigned and rebranded as Mark Levinson models, ending a 14-year legacy of accessible high-end digital audio innovation.
