Form and Function

Small enough to fit in the palm of your hand and light enough to carry in a shirt pocket, the microStreamer was designed with portability in mind. The microStreamer is a USB connected and powered, ultra high-performance external sound card for computers, tablets, smart-phones or any compliant host. Dual purpose built, it incorporates both a high-performance headphone amplifier with an analog volume control that allows you to connect the microStreamer between your computer and headphones; and a fixed-level, low impedance 2.25V line output that allows you to connect between your computer and home stereo, other entertainment system or to powered loudspeakers.

Engineered from the Inside Out

Housed in an aluminum enclosure precision-machined from solid billets, the durable and beautiful microStreamer is modern, sleek and compact. With its jitter-free asynchronous interface, combined with processing power that allows native-resolution (no up-sampling) playback of digital music data up to a maximum of 24-bit/96k material, the microStreamer will transform your computer, tablet, or Smartphone into a better-than-CD quality source. Utilizing native Audio Class 1.0 drivers (present in all modern PC, Mac & Linux computers) there are no extra drivers or software to install.

Portable Optionality

Between the mircroStreamer's USB based power, 3.5mm line output, and built-in amplifier, you've got a lot of good setup options. Toss it in your laptop bag and you've got hi-fi everywhere you go. Couple it with an O2 or a high end portable amp like the the ALO Continental and you've got a complete audiophile setup wherever you setup shop. Starbucks staff will be super jealous and attractive people will use it as an excuse to talk to you.
