Introducing the microStreamer. A revolution in the HRT product line... The microStreamer brings you all the best features of our groundbreaking Music Streamer product with the addition of headphone capabilities all in a miniature sized box that fits easily in your palm or pocket.Hardly bigger than a couple of packs of gum stacked atop each other and housed in an aluminum enclosure precision-machined from solid billets, the durable and beautiful-to-behold MicroStreamer is a thoroughly modern, sleek, and compact dual-purpose-built, USB-powered and connected, ultra high-performance external sound card for computers, tablets, smart-phones, or any compliant host. It combines a 140 mV headphone amplifier with an analog attenuator (just like the HeadStreamer Mobile) with a fixed 2.25V line-level output (50 ohms output impedance), each of which operates independently from the other, so that the user can elect to listen to the MicroStreamer via headphones or through a stereo system, or even have both live at the same time. Each output uses a 1/8" stereo female mini-jack, very common for today's headphones and easily adaptable to standard stereo rigs via a mini-plug-to-RCA adapter cable or an all-mini-plug cable for going into many powered desktop speakers. With sonic performance that places it squarely between the MS II and the MS II+, HRT has, with the MicroStreamer, ensured that there is a suitable device for just about any listener.
