CD1 Manual

CD1 Education Pack

Stereo&Video (May, 2014)
"This amazing group of equipment best demonstrates the audio industry's present state of the art. Internally, this unit is as different from a conventional CD player as a Tesla electric automobile is from a Lada."

Hi-Fi News (March, 2014)
"Thanks to the innovative technology from Holm Acoustics, it does play CDs exceptionally well, and its pure, engaging sound on disc is easily enough to justify the price. Warmly recommended."

Stereophile, John Atkinson (Dec. 2013)
"The CD 1 was the best-performing player I have encountered when tested for error correction... there weren't even any errors flagged in the CD 1's digital output. Color me impressed!"

Stereophile, Sam Tellig (July, 2013)
"The Parasound Halo CD 1 made the most of this recording. I noticed, with this and other CDs, that the string sound was particularly sweet."

Stereophile, John Marks (June, 2013)
"Detailed yet smooth, fast yet not fatiguing, and with wonderful frequency extension at the bottom and top."
