ZDac v2 Owners Manual

ZDac Education Pack (Both versions)

Fidelity (Norway) December 2015
"The price is the nothing less than a miracle. Zdac .2 confirms Parasound's ability to create musical and extremely well sounding products at affordable prices. Here they have worked to achieve exceptional sound from the analog output of all our digital sources, including Apple TV, high res and regular TV sound. No small feat!"

inner Fidelity Gift Guide November 2015
"A compelling experience whether using it with headphones or to drive active monitors in a desktop system."

Stereo+ (Norway), January 2015
"A solid upgrade. The Zdac v.2 does a great job of recreating the full sonic potential of a PC or Mac, and I highly recommend it to anyone using a Sonos system or an Apple TV at home. As we have written previously, the built-in DACs in these devices aren't very good, and with a Zdac v.2 your music will become much smoother, cleaner and more detailed—and far more enjoyable! If you have some expensive headphones that you can't get to sound good with a typical amplifier's headphone output, it will also demonstrate that this device is a real problem solver. Recommended!"

Inner Fidelity, June 2015
"This is a smooth, fatigue-free device which places listening pleasure ahead of micro-detail overindulgence. It feels right at home whether acting as preamp for my Adam Audio active monitors, as a straight DAC feeding my electrostatic setup, or just driving headphones directly as a compact all-in-one."

Enjoy the Music.com (Jan. 2015)
"At $549, this product "sings" and is another example of what the good folks at Parasound are churning out in the way of quality products with down to earth pricing. Be careful though and do not let that modest price tag fool you into thinking it is not all it should be, as it is that and more."

Home Theater Best Of 2013 Award (Dec. 2013)
"The Zdac is a true overachiever whose performance bests that of
much more expensive DACs."

AV Forums (Sept. 2013)
"This is a one of the most refined, controlled and above all, easy to
listen to DAC’s I have spent time with in quite a while."

Audio Fi (Sept. 2013)
"The options at this price range are plentiful but the Parasound Zdac
deserves a listen. With headphone amp bundled in, the Zdac dishes
out versatility and price bracket busting value."

Everything Audio (August 2013)
"The Parasound Zdac is a best buy D/A converter that offers
surprisingly good audio via its line outputs, considering its price."
