AudioQuest JitterBug USB Filter
JitterBug is designed to remove unwanted noise currents and parasitic resonances from both the data (communication) and Vbus (power) lines of USB ports. JitterBug meets all USB 2.0 speed specifications. JitterBug’s excellent performance is the result of careful design and craftsmanship, comprehensive technical measurements, and thorough listening tests.
JitterBug is extremely easy to use and will offer reliable results for many years to come. It can be used with external USB digital-to-analog converters (DACs), mobile phones and portable media devices, and network streaming/storage devices.
- Reduces the noise and ringing that plague both the data and power lines of USB ports
- Measurably reduces jitter and packet errors
- Improves dynamic contrast, warmth and resolution
Partner JitterBug with DragonFly
Slightly larger than JitterBug, DragonFly is a digital-audio converter and headphone amplifier with an onboard 64-step analog volume control. It has a USB plug at one end and a 3.5mm minijack at the opposite end. It connects to any Mac or Windows PC and bypasses the computer’s compromised audio circuitry to deliver cleaner, clearer, more naturally detailed sound to headphones, powered desktop speakers, or complete audio systems. Insert JitterBug in series with DragonFly to further reduce noise and resonances.
- Delivers cleaner, clearer, more naturally detailed music to headphones, powered speakers, and complete audio systems
- Plays all music files: MP3 to high-resolution
- Compatible with Apple and Windows PCs, as well as Apple iOS (5 and newer; requires Apple Camera Adapter Kit) and Android (4.1 and newer; requires Made for Android adaptor)
- Employs high-performance ESS 9016 minimum-phase, 32-bit decoding and onboard bit-perfect digital volume control for the lowest possible distortion
- High output (2.1 volts) drives a wide range of moderate- to high-efficiency headphones
The size and shape of a USB thumb-drive, DragonFly Red is a digital-to-analog converter with a USB plug at one end and a 3.5mm mini-jack at the opposite end.
Compatible with Apple OS X and Windows (7, 8.1, 10) PCs, DragonFly Red can be plugged into a USB port to bypass the host computer’s compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, or complete audio systems.
Thanks to its low-noise, high-efficiency Microchip microcontroller, DragonFly Red draws extremely low power from the host, enabling seamless compatibility with Apple iOS and Android mobile devices. DragonFly Red requires no additional drivers and plays all digital files-from MP3 to high-res (with native resolutions up to 24 bits and 96kHz).
It features StreamlengthTM asynchronous USB code, which ensures low jitter, low resource load, minimal packet errors, world-class audio playback, and reliable connectivity between DragonFly and any computing device compliant with USB Host Mode. DragonFly Red’s 32-bit ESS 9016 DAC chip uses a sophisticated minimum-phase digital filter to provide more naturally detailed and dynamic music, while the bit-perfect digital volume control enables maximum resolution regardless of volume setting: With DragonFly Red connected to a PC or mobile device, adjusting the host’s volume control will adjust DF Red’s onboard volume.
With an output of 2.1 volts, DragonFly Red delivers enough power to successfully drive all preamplifier, integrated amplifier, or receiver inputs, as well as a wide range of today’s headphones, including power-hungry models.
AudioQuest’s free Desktop Device Manager application allows for software upgrades to meet future technological advancements.
With DragonFly Red, music lovers can enjoy an emotionally compelling listening experience, at home or on the go, with the computer or mobile device of their choice.
