"SB Touch...buh bye. Hello Android Media Box…

Plug and play USB audio support - no drivers, no snap crackle pop, no dropouts. Wow. The sound was absolutely fantastic. What a great way to consolidate my favorite streaming apps and have my ripped collection just a click away as well. All controlled remotely from the comfort of my easy chair and viewed on my big screen TV. I AM Slothman!

In summary, this was all an exercise in music listening convenience for me and obviously NOT an audiophile quest. However, I do believe that devices such as these and the applications being developed are on the verge of further revolutionizing this hobby in a big way soon. After my initial experience with this (basic) media box, I can certainly see why Logitech decided to kick the SB Touch to the curb. I hope this thread may spark a little more discussion and interest in these Android media boxes/ mini PC's. I haven't seen much mentioned about them here or on computeraudiophile."









With Android phone, Android tablet and Android mini PC, Android is definitely a New Kid in Town for the USB DAC market sector.

I ordered the HRT Headstreamer. I should have it tomorrow. Hopefully that works.
post #125 of 206
According to HRT there is a difference between the Headstreamer and the Headstreamer Mobile. Perhaps that designation should be used in the list as it is said on their website that the Headstreamer Mobile will work with the Galaxy S3.smile.gif
Quote:
If you listen to music on headphones via a computer, iPad, Surface tablet or a Samsung Galaxy S ll or lll phone and want better sound quality then HRT's HeadStreamer Mobile is the perfect solution. Technically, HeadStreamer Mobile is a USB-connected and powered dedicated headphone amplifier/sound card designed to seamlessly interface with PC, Linux, and Macintosh computers, iPads (1, 2 & 3), Microsoft Surface tablet and the Samsung Galaxy S ll and lll phones. It directly decodes the digital music data stream from the computer, tablet or phone's hard drive into analog music for headphone listening. Like other HRT products, set up and operation is super-easy: just use the included USB cable to hook the USB input of the HeadStreamer Mobile into any available USB port on the host computer*. The HeadStreamer Mobile automatically performs an "electronic handshake" with the source device and tells it that the HeadStreamer Mobile is here, that it is to get all audio signals sent to it instead of the Digital-to-Analog converter (DAC) that is built into the computer, tablet or phone... And that's it, the HeadStreamer Mobile, is in charge of all data-transfer timing instructions. Then just plug your headphones into the 1/8" analog output jack on HeadStreamer Mobile. Now you are ready to stream some music, either directly by playing a disc through the computers optical drive, or read as a digital file from your computer, tablet or phone's hard drive. You will literally never need a stand-alone CD player again to enjoy all the music in your CD collection in high quality sound through headphones. If you happen to have other higher-resolution files (up to 24bit/96k) stored on your HD, you can also play them in their full native resolution (no up-sampling).

I think they are the same device.
By the way, now "HeadStreamer Mobile" is only mentioned on the HRT website.

Any recommendations on getting more output from the preamp of the Note 2. I find that I have to turn up all the way on certain recordings to get audio at good dynamic levels. I have tried Hot Mod (doesn't seem to do much, I am rooted by the way) but not much if any improvement. Interesting on the HRT. When I called them last week they said there is a difference between the two. I don't remember what though.

"I need to say this: driving my Audeze LCD3's with the microStreamer (not the easiest headphones to drive well enough to truly show their magic) had me talking to myself when I first heard the magnificent combination! My wifey would hear me saying things like, "this can't be ******* happening," and "this is unreal"...

The HRT microStreamer has raised the bar so high in its category I hope it gets all the accolades it deserves. In uber-portable headphone amp/DAC combo solutions for the computer I can't think of another component outside the Audioquest Dragonfly, which to my ears doesn't have quite the dynamic punch of the microStreamer that even approaches the sonic performance of this miraculous little aluminum brick. It's like an audiophile’s reference-system-in-a-box. You have to hear it to believe it."

If I'm seeking superior audio quality from my phone on my home theater system what would be my best option? Essentially, how would I best connect my Samsung Galaxy Nexus via usb audio to my home receiver (Onkyo 706 FWIW)?

The Samsung/Google Galaxy Nexus can only output a digital audio stream when using the USB Audio Recorder PRO app, which is basic for the time being.

Very interesting topic!!
DanBA are you aware of any quality sound docking station out there that may connect to our Android phones? Possibly with a quality DAC onboard, pissibly without the cable hassle:

I was thinking about potentially getting a USB DAC for my Galaxy SIII, but then I got to thinking...

I have an operational MHL adapter for my phone and a Sony STR-DH820 receiver. I attempted to connect the phone to the receiver and listen through my speakers. It worked after some finagling. I had to make sure that there was an actual monitor connected, powered on, and displaying the phone's screen, or else the phone would eventually revert to powering its internal speaker. The receiver reported the audio was LPCM 48, and it definitely sounded better than simply connecting via the headphone jack.

I'm still interested in attempting to use a USB DAC, but I'd like to begin with an inexpensive one in case I find the increase in fidelity just not worth the price I paid. Or I could just get from Amazon a FiiO Andes E07K and return it if I'm not satisfied.

I think I need to explore my options a bit more...

The Samsung Galaxy S4 smartphone battery is spec'd as: 3.8 Volt, Lithium Ion, 2600 mAh

If I remember right, the USB connectors run at 5 Volt? So the S4 adjusts the voltage on the USB connector to 5 Volt? Or simply runs it low at 3.8 Volt?

Given that the S4 is driving the FiiO E17 DAC/amp and the Sennheiser HD205 headphones, what's the ballpark of number of hours that the S4 battery can play music for?

Is this with compressed mp3 music files from the S4's memory card?

Are there any "hiccups" with playback of these less demanding music files (smaller amount of data)???

My own limited experience with laptop music playback (16/44.1 .flac files) from memory cards (laptop w/ either SDHC and SDXC), and USB memory sticks, is that the playback has occasional glitches or hiccups. Is that also the case w/ music playback on the S4 and other similar good smartphones like the iPhone5?
