If you are an Audio Geeklike myself you'll appreciate this little thing. I can't say yes or noto the compatibility with the iPod Classic 160 Gb (7th Generation).You can probably contact HRT directly and get the answer straightfrom them. www.hirestech.com. I can only praise it for what itdoes for me. It has worked flawlessly with my setup. If you want crispnessin sound and have an ear that appreciates what you hear I can onlygive it another thumbs UP. I am still using it with my Shure 950's.It does make a big difference for me. As far as convenient, its anotherlittle thing that hangs out of my USB port. I got use to it. It's benefitsout weigh any little nuisances I thought it may have had at first. I am sureif you like music and this thing delivers what you want you forgetabout anything else. It lets me hear things that I have not heard on the sametracks that I have listened to for many years. Maybe someone can answer yourquestion about the compatibility with your particular iPod. No matter what you use it foryou won't be disappointed. Thanks - Mark K **Q: Can you plug this into the lightning port on iPad and play music without a computer (portable)???** A: Yes, with an adapter, it should work. The description also states that it is meant to work with an iPad. I use it on a computer (imac) by the way, and the sound is incredible. Update the firmware if you get it (http://www.hirestech.com/support-download/ - it is the zip file at the bottom of this page), but don't fret if you can't. It sounds great. **Q: What dB gain will I realize with the built-in amplifier?** A: Built in Amplifier, Gain - I have no way to answer those questions, they make no sense for this application. Perhaps what you are looking for is the output amplitude. The HRT website lists the output as 1.4 volt, 130 Milliwatt output at less than 1 ohm output impedance. The theoretical load resistance for 130 milliwatt output is 15 ohms, so the load should be above 15 ohms. It makes a good source for earphones and boom boxes. I use the Headstreamer with Bose QC 15 Quiet Comfort Acoustic Noise Cancelling Headphones and Sony MDR-V6. There is pleanty of output to drive painful earphone volume. The QC 15 is nice because a nagging wife can't be heard. I use the Headstreamer to evaluate music from CD's before loading to the Cell Phone. I use Motorola S305 Wireless Bluetooth Headphones with the Cell Phone (it even answers calls). Not quite as smooth as the Headstreamer, but very acceptable. I find FM radio to have extremely low quality in general and use the Cell lPhone for most listening. HRT has been very good at answering e-mail questions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Excellent device for audiophiles *by V***X on Reviewed in the United States on October 3, 2012* I moved to the HRT HeadStreamer after using a Fiio E7; it was like a breath of fresh air! In my setup, the E7 had a low-level 60Hz hum when powered from USB. This was quite noticeable when listening to high dynamic range classical music at high volume.The HRT by contrast, is quiet and clear. No hiss, no noise, only crystal-clear music. I use it to review piano recordings; these are of good quality, with a low noise floor. The electronics in the HRT are so quiet that I can hear the (low) noise in my recordings, and can hear fine nuances of the recording such as mechanical sounds, the ticking of a small clock several feet away, etc. And when the music gets loud, the HRT has no problems delivering crisp, clear notes across the frequency range, at ridiculously high volumes.Installation was a breeze on my W7 64-bit PC, just plug and play. The HRT even works fine through a USB hub. My source material is typically lossless WAV files at 44.1KHz or 48KHz; I adjust the Windows output audio sample rate for the HRT to match the source material to avoid resampling losses.Compared to the E7, the HRT costs more and has a minimalist design with fewer features: No cute screen or buttons, no built-in battery or capability to be used as a standalone analog headphone amplifier. But it does one thing really well: Deliver clean and crisp audio. To me, that's everything, so the HRT is well worth its price! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Amazing little DAC/amp -- UPDATE: Now Discontinued *by A***. on Reviewed in the United States on January 5, 2013* For years, I've done most of my listening via DAC and headphone configurations, streaming lossless files from my computer. I have a HeadRoom Desktop amp with their DAC circa 2006. I was an HRT early adopter, however, and picked up the original MusicStreamer+ back in 2008. That was a great product, and the company let me upgrade it to a MusicStreamer II+ at a steep discount last year so I could get the benefits of their new asynchronous USB circuit. (I tell you this because, during that process, I was in direct contact with Kevin Halverson, the company's owner, who is quite enthusiastic about bringing great sound to people at reasonable prices. Great service!)Anyway, when I wanted to get a portable amp so I could listen at work, I went back to HRT, having been impressed with their low-cost solutions in the past. The HeadStreamer lives up to the excellent reputation the company has been earning.I listen with a set of AKG K240 Mk.II headphones at 55 ohms impedance and stream FLAC encoded files at 16/44.1 and 24/44.1 from a machine running WinXP 32. This little DAC/amp does them justice. The sound is detailed and clear, with actual separation of instruments. The bass is tight and controlled and sounds great on the AKGs. Mids and highs are clear without being harsh.My only complaint is that I sometimes get a bit of lag/computer induced distortion when switching files in Outlook. No WASPI in WinXP 32. (I have no similar problems using the HeadStreamer on my home PC running Win 7 64 and using WASPI.) That isn't the fault of the HeadStreamer, though.In all, this and a decent pair of headphones will give you amazing results and bang for your buck for less than you would spend on an entry-level consumer grade home receiver and speakers. If you really want to hear well into your music, check this little wonder out.-------------UPDATE-------------This product is now discontinued by HRT in favor of their newer MicroStreamer, which, like the HeadStreamer, is an outboard DAC and headphone amp. However, the MicroStreamer also has a line level output that makes it suitable for use as a line source for a home amplifier. It's a bit pricier, so you still might be interested in snapping up one of these excellent little HeadStreamers before they're all gone. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Clean out your ears! Stoneage computer audiophile era NOW! *by M***O on Reviewed in the United States on March 8, 2012* We are in the stone age of the computer audiophile era because these are the early USB/DAC devices that a becoming more and more mainstream as we more often use our computers to play music. As the previous review noted, the prerequisite is Foobar with WASAPI plug in. There are some issues with Windows and USB control because if you have Foobar open, Flash plays from the computers speakers or if you have a 3rd button mouse, you get intermitten interference. So, a computer setup only for audio would be ideal.First Impressions: Assuming that you did the Foobar/WASAPI installation, and know what your computer is capable of, which in newer computers, is very good, only then you can experience better sound. Most of the econo USB/DAC's may be only marginally better than a modern laptop. Since my laptops are relatively new and have upgraded audio capability, some lesser DAC's did not improve sound quality enough to even justify their lower price. Although not terribly expensive, the Head Streamer uses similar technology that is seen in devices costing at least 2x or many multiple times more.The sound is dependent on your output device, but on the whole it gives a wider soundstage, a deeper soundstage, a warm midrange, extended, but not shrilling highs. Bass is extended and has some more detail than what I noticed with my stock laptop with WASAPI output. (Of course, stock laptop sound from Windows default sounded compressed with limited dynamic range) My full size headsets sounded much fuller and more dynamic, but it may have overpowered my IEM headsets because the sound became a little flat. Vocals have a smidgen of Pidgeon warmth to it that is very pleasing. I am still getting used to the wider, cleaner, clearer sound, but like anything else, it takes time to get over the shock value and just to enjoy the music. Like a new pair of glasses or your ears popping inflight an airplane, everything just sounds new again so it will be nice to review them again after some time.EDIT: Been busy and I don't know about burn in, but I just realized my onboard laptop DAC is no slouch. The HeadStreamer sounds wider and more extending both ends, but only if you have better headphones or a very quiet listening environment. I could not imagine another product to significantly better the sound when you listen with better equipment. The only drawback is that my laptop has the occasionally USB interference or Iphone radio interference- who knows. Vocals are no longer veiled, highs become more transparent and bass becomes more detailed/textured. I have never heard cleaner, both clearer and smoother sounds from my digital files. Of course the better the output device the better the results. At this point, I think I maxed the quality for relatively low cost.
