Ayre QB9-DSD DAC (with 5 Upgrades to the Original)


In excellent condition and works perfectly. The sound is glorious, very refined and engaging. Fully balanced circuit design. Can handle the following types of signal: 16, 20, and 24 bits / 44.1, 48, 88.2, 96, 176.4, and 192 kHz / DSD

Retailed at $3495 and heavily upgraded from the original version, this is so much more than a QB-9 that plays DSD files. To know about the five upgrades they made to the original, please read the information down below.

The price is firm. Comes with manual, USB cord, power cord and original packaging. I upgraded so I no longer need this.

Buyer pays shipping and Paypal fees if incurred. Using "To a Friend or Family" option, there will be no fees. I also accept Venmo and Zelle.

Information from audiophilestyle.com
“The Ayre QB-9 DSD is so much more than a QB-9 that plays DSD files. The QB-9 DSD contains five upgrades from the previous model, the smallest of which is the enabling of DSD playback. The QB-9 DSD is really a completely new DAC. Ayre changed the DAC chip from the Burr-Brown DSD1792A to the ESS 9016S. The second upgrade was replacing the audio master clocks with low phase noise modules, that run at double the frequency of the previous modules, enabling the new ESS chip to perform at a higher level. Third, Ayre improved the analog audio circuitry and power supply for increased performance. The fourth upgrade was the addition of an AC line powered supply for the USB circuitry. Computer audiophiles take note, this upgrade makes a computer's USB bus power irrelevant. The QB-9 DSD doesn't require any power from the computer. Last and definitely least, the QB-9 DSD now handles DSD64 material. Don't get me wrong the QB-9 DSD plays DSD music wonderfully. I just don't want readers to get caught up in the numbers game and assume this major QB-9 upgrade has much to do with DSD playback when it's really about the other four major improvements...The QB-9 DSD may have the best all around USB implementation of any DAC I've ever used.”
