New and improved, the ARC Audio PS8 includes a completely new feel for this true audiophile-grade signal processor. Already an existing PS8 owner? No worries! The latest software updates offer higher levels of refined operation, as well as some new and improved features, and available to everybody at no cost.

Offering the most comprehensive and highest resolution audio capabilities available on the market, ARC Audio has once again raised the bar with the creation of the most advanced audio DSP available for consumer use.

From the combined efforts of Robert Zeff, Richard Greenway, Brad Ott, Fred Lynch and contributions from the championship ARC Audio sound quality competition team, the PS8 offers the most advanced solution to putting the power of tuning and creating that personalized musical experience back into the user’s hands.

Designed, engineered and manufactured exclusively in the USA the PS8 is built with only the highest quality handpicked electrical components from the USA, Europe, and the UK. With design features including 4-layer gold core PCB's, ARC Audios exclusive M.I.N.E.R.; ground isolation technology, audiophile designed ultra-high frequency switching power supply, Ultra high performance exclusive audio grade DSP, proprietary DSP source code exclusive to the PS8 and a first of its kind auto recovery USB DSP technology gives users the assurance that they will only experience the most transparent, most natural, and most realistic sound of any DSP on the market!
