“With the SP20, Audio Research Corporation strides surefootedly back into the market of high-end preamplifiers. While not at the rarefied level occupied by ARC’s Reference components, it’s a big step up from the SP16 and SP17, and enters the territory occupied by ARC’s best non-Reference phono and line stages.”

I got similar results with the Tallis Scholars’ recording of Allegri’s Miserere (24/96 FLAC, Gimell): The SP20 made it easy to hear the instrumental details in this information-rich recording, as well as the precise positions of singers across the soundstage.”
