In 1984, Mark Levinson founded Cello, Ltd. to go beyond the limits of current audio playback. The first product of Cello, Ltd. was the Audio Palette, the world's first state of the art equalizer, designed to fine tune music program material to obtain the most natural sound. Today, vintage Audio Palettes sell for USD 15,000 20,000 if one can be found.

Audio Palettes were used by both residential listeners and professional studios like Polygram, BMG and Atlantic, Records. Based on specifications developed by Dick Burwen, Mark's electronics mentor, The Audio Palette had a dynamic range of 110dB and other phenomenal performance specs. The Audio Palette contained over 6,000 parts, 48 discrete amplifiers, and handmade 59 position rotary controls using 1% tolerance metal film resistors. Hand engraved panels and knobs represented the ultimate in cosmetic refinement and elegance. The new price of the Audio Palette at the end of it's production was USD 25,000.

Daniel Hertz now introduces Master Class, the digital version of the Audio Palette, with even higher performance and many cool features like the ability to store and load playlists and presets, and to print new AIFF files with all changes embedded. Master Class also offers A+, an algorithm that fills in the steps of the PCM waveform with original musical information, to obtain a more enjoyable analog-like listening experience from standard digital audio formats.
