Android phones and USB DACs - Page 109

Today's Woot! is refurb Galaxy Note 10.1's and they're about $100 off normal price.  It's been a while since I've seen anything about them in this thread, does anyone know if they have the DAC support that the SIII and Note 2 do?

No custom configurations or setup needed, just plug right in and the phone sets itself up. 

 

I will not ever touch fast charge, since that killed my old motherboard. 

Which S3 / ROM / DAC?

I have a US Galaxy S3 (i747), using liquid smooth, assuming it's the stock kernel since I don't think liquid smooth comes with a kernel, flashed the norris audio patcher, ran usb audio pro (no other music player got audio out via usb) trial, and it does work, but glitchy choppy audio into a Fiio E17 via usb otg cable.

There's gotta be some hope somewhere that the US S3 -> otg -> e17 should work via software changes since this setup does output some audio (not very good quality yet though)

I'd also appreciate an answer to this. Right now, I'd probably only bother buying a mini HDMI to HDMI solution (and a subsequent HDMI switcher for the monitor) to use with my android device so I can watch HD music videos on an external monitor. However, since the audio quality is top notch, I'd still rather use an external USB DAC for the audio. Can one use an external USB DAC (audio) & HDMI (video only) simultaneously?

Thanks

Like the HRT microStreamer’s USB DAC, my ODAC is bus-powered. 

When connecting the ODAC to the smartphone via a Belkin self-powered USB hub, the power to the ODAC is no more supplied by the smartphone, but by an external power supply: external battery or mains power adapter.

 

smartphone >> USB OTG cable adapter + USB cable provided by the USB hub manufacturer >> USB hub >> USB cable provided by the USB DAC manufacturer >> USB DAC

 

smartphone >> micro-A plug to standard-A receptacle USB OTG cable adapter + standard-A plug to mini-B plug USB cable provided by Belkin >> Belkin 4-port USB 2.0 hub >> standard-A plug to mini-B plug USB cable provided by the ODAC "manufacturer" >> ODAC

 

USB hub << power cable << mains power adapter

or

USB hub << power cable << Veho Pebble USB battery

Quick question, DanBa.. In the part I highlighted in red: does the Belkin hub you're using have a usb mini-b (female) port?  I thought you need to use a "usb-a to usb-a" cable between the OTG adapter & the hub?

Yes, my 4-port USB hub has one mini-B receptacle for the upstream port connecting the USB hub to the USB host, and four standard-A receptacles for the downstream ports connecting the USB hub to the USB peripherals.

"The following list explains how the plugs and receptacles can be mated:

Danba, you've been quite keen on using battery packs with your portable rig.  The theoretical improvements are certainly there.  And I know power conditioning can, at times, greatly improve the performance of some desktop gear.  But does it really make an audible difference with these portables?  I've yet to hear either the Pico or Headstreamer sound any different connected to any device, be it computer or phone.  But I've not had a chance to try one of those battery packs, so I can't say with authority.  Rather, I remain skeptical.

ok guys... I swear I started reading this whole post to try and find my answer but when I saw 109 pages I accepted my defeat ;o)

I am a complete noob to quality cans.  I just bought an internally modded D2k from swimsonny.  I am very excited but I also would like to get an amp as I have been told they help greatly with the D2K's.  I am normally hiking or outside in a hammock.  I want a nice one but portability is important...

What do you guys recommend?

Thanks

Wrong thread.. hell, wrong sub-forum.  Swing and a miss, bro.. restart your computer & try again.

Hey man. Here's a couple of points that might help you along: 

1). The D2ks are great headphones (according to their reputation), but they are not going to be much good at all for something like hiking. They won't stay on your head particularly well and they leak sound like a mug. Might work for the hammock though!

2). What kind of source device (= probably your phone) do you have? Right now there are only a handful of phones that will allow the use of an external DAC, so if you don't have one of those, it will completely change the answer you get here. This thread in particular is about the devices that work with external DACs, so if you don't have one of those, you'll probably find better information elsewhere. 

3). What's your price range? As with all things in life, what you get is largely dependent on how much you're willing to spend ;)

4). If you're looking for answers around Head-Fi, there are a TON of threads, subforums, links to other sites, etc to navigate around. And frankly, the search function here isn't worth a hoot in my opinion. So if I'm looking for something on HF, I'll go to Google, type in what I'm looking for, and add "site:head-fi.org" to the end, so Google will search HF for that string. For example: "denon d2000 portable amp site:head-fi.org", although you don't include the quotation marks. I've found this to be VASTLY more useful than the general search function here. 

5). And in case nobody's told ya yet: Welcome to Head-Fi!!! Sorry about your wallet 

It might be good to do the Googling first and then come back with some questions once you've done a little reading. (If you need help figuring out where to look, PM me and I'll try to point you in the right direction). Congrats on the new cans!!!

Correct on all counts, they are not portable, and will fall off your head, don't isolate too well, and leak sound. They also aren't built tough, and the cable is too long and inflexible for portable use. 

There is a link in my sig explaining what to look for in amps for Denons. Start their, but not many portable amps are mentioned - because its not a portable can. But from there you will know what to look for.
