Product Description

Housed in an aluminum enclosure precision-machined from solid billets, the durable and beautiful microStreamer is modern, sleek and compact. It is simple to use and provides a level of improvement in sound quality that must be heard to be believed. To improve your computers' sound quality, the microsStreamer takes over the job of processing the digital music stream from the computer - a task critical for producing great sound. Do not be fooled by its modest cost or small size: the microStreamer's ability to transform the sound of your computer, smart phone or tablet's music files or streaming audio into a state of the art musical experience will make a believer out of even the most critical listener. As with other HRT products, the set up and operation of the microStreamer is super easy: simply use the included USB cable and hook the input of the microStreamer into any USB port on the host computer, smart phone or tablet and select it as the default outpost device. Now you are ready to experience your music with the best sound possible. Operating jitter-free via the use of its high-performance asynchronous USB transceiver, the microStreamer, when plugged in, automatically performs an 'electronic handshake' with the computer or other host and tells it that the microStreamer is to get all audio signals sent to it instead of the Digital-to-Analog converter (DAC) that is built into the computer, and that's it! To enjoy the music in your home entertainment system optimally, connect the microStreamer's fixed output jack* to any available line-level analog input on your integrated amplifier, preamp, receiver, or powered loudspeakers. Alternatively, connect your favorite headphones to microstreamer's variable output port.

Even my SACD rips, recorded very quietly, play loud enough for me.
It works great when connected to my computer, but it really shines when connected to my iPad (via a Lightning to USB Camera adapter).

It's sound is smoother, perfect in tone, and has great detail retrieval.

When I connected the HRT MicroStreamer to my PC and Mac computers I was pleasantly surprised that it interfaced perfectly with no configuration effort. The MicroStreamer is a very small USB device with a mini-USB jack on one end and two 3.5 mm jacks for headphone and Line Out on the other end. I confirmed that the Line Out jack delivers the same signal (audibly) as the headphone jack when the computer and music player volume are set to their respective maximums. With this "repurposed" digital volume control, where the system volume is actually taken over by the DAC so that decreasing the volume doesn't compromise audio quality, it's generally advised to keep the music player volume at maximum and use the system volume slider only.

HRT supplies a 19-inch USB cable with the MicroStreamer, which I replaced with a 12-inch cable. Since the asynchronous DAC re-syncs the bits after they arrive at the DAC, I assume a short USB cable should suffice to preclude any cable-induced losses. On the other hand, when using the Line Out jack to feed the DAC's analog output to a headphone amp or power amp that has its own volume control, that interconnect cable should be as high in quality and as short as possible.

The key feature that distinguishes this mini-DAC from other audio devices that perform the same function is having a DAC and headphone amp** together in one little plug-in device. For people who have been using the headphone jack on their desktop or laptop computers, and assuming that those computers have USB ports, they should expect better sound using the MicroStreamer instead of the computer's headphone jack. The actual improvement with my computers is a cleaner sound with a greater sense of "space" and "air" around the instruments.

[I'm raising my review score from 4 to 5 stars, even though 5-star reviews are often uncritical. This tiny thing, and its creator Kevin Halverson, deserve it]

It should go without saying that the Microstreamer will sound better than a built-in PC (or even Mac) DAC, so the fact that so many reviewers use that as their point of comparison says that they're taking a first step toward computer hi-fi. They took a big step with the Microstreamer, actually, and those folks shouldn't go chasing better too quickly, because it'll be hard to find (note that this only applies if you have made an investment in your headphones: probably anything under $100 that I know of won't benefit). A better question for me was, how does it compare with the USB/DAC/headphone amp path built into my integrated amp? On first listen, short answer was that it makes my integrated amp sound like it was playing from inside a sack. Not a thick sack, maybe, but still. It's really a surprise to be so used to "emaculate" sound on good headphones (Grado SR-225i, then later Beyer DT-880 and HifiMan HE-400), and then after 1 minute with another...ummm... "rig"... go back and never be able to hear one's old amp the same way again. The best thing I've done with this doohickey so far is play "Young Person's Guide to the Orchestra" (24/88.2, Michael Stern & Kansas City Symphony). The initial boom of bass drum brought out a literal "oh, wow," and the sense of space thereafter was really impressive. I felt like I was hearing music more clearly than I've ever done. This may actually be as detailed as you can hear music. If there's room to put any more detail onto tape or hard drive in the studio, I don't know where.

I was skeptical about whether I would really hear a noticeable difference but read too many good reviews about this HRT and DACs in general.I have a Windows 7 PC with Bose Companion 20 speakers (I think very good two hundred dollar or so PC speakers). I have a middle of the road sound card in the PC. I thought I was getting good sound when I played back my 1960s and 1970s music - the source either being ITUNES Apple lossless or YouTube videos.

From the very first song I listened to after connecting with the HRT (less than 10 seconds to connect, and really NO special drivers or software to install) I was blown away, simply amazed. The sounds are so clear and natural. I am shocked it could improve the sound quality THAT much. I don't listen with headphones so I can't commnent on that, but for a PC with good PC speakers the improvement and increased enjoyment I am getting is sensational.

Sound quality: did extensive blind listening comparisons with well-regarded ODAC+O2 amplifier combo, and could not hear any differences. That, combined with the measurements (trusting the manufacturer on those) means this device is sonically transparent -- it's not adding to or removing anything from the sound, and you're hearing it as it was recorded. Noise floor is not audible even with very sensitive Etymotic MC5, which made them usable with MacBook Pro (whose own noise floor is audible and bothers me at low volumes).

Convenience: small enough to carry in my pocket. Does not require charging or batteries.

Versatility: works with all my computers, iPad Retina (requires camera connection kit), iPhone 5 (requires camera connection kit & iOS 7).

Customer service: I contacted High Resolution Technologies via their web form asking for more detailed specs regarding power output for various headphone impedances, and got an exact answer from the CTO in about an hour. Asked a follow-up question and got an answer almost instantaneously. This is much better than my typical experience with other companies' tech support, as usually first-level reps are not technical and can't help with anything that's not in their script.

Specs: Most impressive is .5 Ohm output impedance. This means you can drive low-impedance headphones (like above mentioned Etymotic MC5 at 16 Ohms) without changing frequency response and providing sufficient damping factor to provide tight bass.
