Other Notes: 

"The Ayre Acoustics QB-9 Twenty features an ESS ES9038Q2M chip, PCM up to 384 kHz, Native DSD256, and AyreLock power regulation. This 5-pound USB-only DAC uses proprietary asynchronous tech to eliminate jitter, boasting a complete internal overhaul with elite R and 8 series technology. Audiophile Style reviewers rave about this "remix," noting its drastically lowered noise floor and improved musicality. The new JFET differential stage and Diamond output circuit deliver superior spatial detail and robust bass response.

Critics highlight its lifelike sound, praising the "analog-like" midrange and enveloping soundstage that makes speakers disappear. While strictly a USB DAC—optimizing pure signal processing over legacy inputs—users consistently celebrate its natural timbre without digital harshness. It renders fine musical textures with stunning accuracy. The QB-9 Twenty offers a world-class, immersive upgrade that will beautifully transform your digital audio library."
