Perpetual Technologies was founded by Mark "Shifty" Shifter and Hi-fi Buys co-founder, Walter Liederman, Perpetual Technologies picked up where the legendary Audio Alchemy left off. Perpetual made audio components like digital to analog converters and other small format audio products.

While sold for a while at AV123.com, it looks as if Perpetual Technologies are no longer being made or sold. The Perpetual Technologies website is now owned by an IT company.

Notable products included the P-1A Digital Correction Engine and P-3A DAC. For a review of these on Secrets of Home Theater, click here.

Other engineers from Audio Alchemy went on to form Channel Island Audio (which is still in business)
