User Manual



audiostream_ayre_qx_5_twenty“…It makes it listenable because it doesn’t unnaturally over-emphasize anything. This naturalness is the case with a rare breed of digital in my experience and the Ayre QX-5 Twenty joins that list with ease. Of course, it does fine with fine-sounding recordings, too.” — Michael Lavorgna (Audio Stream — November 2016)



Soundstage-HiFi-Ayre-QX-5-Twenty“… What I can say is that the QX-5 Twenty is a beautifully designed, well-built component that could easily anchor a state-of-the-art sound system for years to come. No matter how you play your music, it will accommodate all of your digital sources … I expect that those who buy a QX-5 Twenty will spend a lot of time revisiting their music libraries, just to hear how good they sound through the Ayre. Any component that makes you want to go back and listen to music you know and love, just to rediscover it, is special indeed, and the QX-5 Twenty fits that description. Highly recommended.” — Philip Beaudette (Soundstage! Hi-Fi)
