ESS Sabre32 DAC Technology
ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequalled dynamic range, ultra low distortion and unmatched audio clarity free from input jitter. While ESS Sabre32 DAC has been widely recognized and employed in the audiophile community as the next step in converter technology, Apogee is one of the first pro audio manufacturers to employ this DAC in an interface designed for audio and video professionals. ESS Sabre32 DAC technology, as employed in Duet 2, Duet for iPad & Mac, Quartet and Symphony I/O, is one ingredient in the Apogee Engineering Difference. The benefits of the ESS Sabre32 DAC include:

32-bit DAC Architecture - Compared to older 24-bit technology, the Sabre32 DAC's 32-bit filter processing results in significantly lower noise and distortion, for a pure listening experience free from artifacts. 32-bit digital attenuation ensures that sonic purity is maintained at any listening level.

Time Domain Jitter Elimination - removes clock inconsistencies from the incoming digital data, so the converted analog output preserves the clarity and soundstage detail of the original recording.
