A headphone amplifier with integrated DAC
What does the Opus#11 have to offer? This headphone amplifier with integrated digital-to-analog converter (DAC) is designed to be paired up with a computer, smartphone or tablet (iOS or Android) for digital audio playback. Equipped with its own battery, the Opus#11 will not drain your smartphone?s battery once it is connected to the latter?s USB port. The integrated battery provides a very steady power supply, optimizing the Opus#11 operability.
Technical characteristics
The Opus#11 is compatible with PCM audio streams up to 24 bits and 384 kHz, making it possible to listen to very high-resolution FLAC files in addition to MP3 and AAC files. DSD audio streams up to 5.6 MHz are also supported, enabling the playback of DSD files extracted from an SACD, for example. The Opus#11?s DAC is none other than the ESS Tech Sabre 9018K2M, a highly energy-efficient chip with a reputation for providing superior performance. The USB controller is manufactured by XMOS, a brand which has become a leader in the audio processing field over the course of the past several years. TheBit claims that the Opus#11?s 1400 maH battery provides approximately 8 hours of continuous playback. Its 3.5 mm mini-jack headphone output produces up to 2.1 Vrms of power, or approximately 2×140 mW for a pair of headphones with a nominal impedance of 32 Ohms. The Opus#11 headphone amplifier can power headphones with impedance levels ranging from 50 to 100 Ohms without any difficulty.
Connectivity and ergonomics
In terms of connectivity, the Opus#11 presents us with a 3.5 mm mini-jack stereo headphone output, a micro USB port and an optional 5V DC power adapter input. The Opus#11?s front panel features two LED indicators: one to indicate charging status and the other to confirm data transfer between the DAC and the source (computer, mobile device). The Opus#11 comes with several micro-USB cables (smartphone, computer). However, an iPhone-compatible cable is not included.
