Audio-Opus OPUS #11
Ultra-Slim DAC/Amp for Smartphones
A portable amplifier and USB DAC rolled into one, the Audio-Opus OPUS #11 is designed to help you get better music out of your iOS or Android device. The gold-finished brushed aluminum body is smaller than the average smartphone and just 7.9 millimeters thick, ensuring it slides easily into your pocket and fits comfortably in your hand. Pair it with your favorite IEMs or full-size, low-impedance headphones, and enjoy up to 8 hours of playing time between charges. Equipped with a Sabre ES9018K2M DAC, the OPUS #11 delivers excellent sound quality and support for PCM formats up to 32 bit/384 kHz, as well as DSD64 and DSD128. It’s no wonder one Head-Fi reviewer calls it “an easy recommendation” and “the best DAC/amp combo I’ve come across for less than $649.”
Note: Please note that the OPUS #11 has no volume control. Instead, volume is controlled on the source you're plugged into.
