    Cool, so you have your music stored on the USB HD, any difference in sound between files on the HD and those stored locally on the phone? THanks
     
  3. m-i-c-k-e-y
    None that I have noticed... And the plus side is that, I could bring with me lots of DSD music.

    Can somebody recommend a cheap battery powered thumb sized dac preferably without an amp that supports native otg usb. By this I mean works with any app and not just in usb audio player pro. I'm running lollipop on my lg g3. Thanks in advance.

    I already know about the hifime but thanks for the recommendation RamblerBoy. I'm looking for a dac that is higher quality and is battery powered so to reduce battery drain from my phone. 
    I'm interested in the alo audio usb key but cant find many feedback from buyers. Doesn't seem very popular and it also isn't battery powered.

    HRT-DSP is very good and cheap. It has no battery, but its power consumption is negligible.
     
  8. m-i-c-k-e-y
    USB DAC w/ battery now current in production...
     
    The only thing I can thin of is Encore mDAC: http://www.head-fi.org/t/736452/review-encore-mdac-portable-headphone-dac-amp-with-24bit-96khz-usb-input-for-mac-pc-iphone-with-camera-connection-kit-and-android-2-thumbs-up
     
    If you want (higher quality) you have to wait...maybe and yet maybe this summer..the company has fulfillment/QC issues LH Labs Geek Out V2+ / V2+ Infinity: http://marketplace.lhlabs.com/products/geek-out-v2-usb-dac-headphone-amplifier

    htc microstreamer seems like a good choice. It has a dedicated line out jack that completely bypassess the circuitry of the internal amp. Arrhh I'm spoilt for choice. However I'm not sure if it supports all apps. Also not sure if Full Scale Output: 2.25 V RMS (line), 1.4V (headphone) really means only 1.4v for headphones and 2.25vrms only for speakers?

    I decided that it was the new phone's day for another attempt at USB audio out. It had not worked well for me with the lost-in-a-flood mi4i, so now for the Moto X Play (Marchmallow 6.0)...
     
    At first, my experience with the X Play was much the same as with the m4i, except the GO V1 (450) worked, at least for a while, as did the little HiFiMeDIY thing.
     
    I've been having trouble with this USB out on several devices, and slowly, the idea bloomed... try a different OTG cable. Ha! Basic, eh? Well yeah...
     
    And Moto Play X to Geek Out V1 450 just worked. Brilliant. But, drawing lots and lots of amps (heck, remember it has to heat the room as well as make sound!)
     
    Time for the Plugable 4-port Universal Charging Hub. It should certainly be able to produce the amps, although I have no clue how a DAC tells it how many. But No Go... Device not recognised. Surely a hub should be transparent? if this thing works direct, it should work with the hub, shouldn't it?  OK, probably the answers are in the 500-plus pages of this thread.
     
    Anyway, it occurred to me to try the Plugable  with a thumb drive, which is pretty basic for a hub --- and I didn't see that on the phone. Then I get a question about Allow device to access USB (paraphrased), and having confirmed, then thumb drives are visible on the phone.
     
    Curious thing: plugged in the DAC again and it just worked.
     
    So, after some time, I'm back here on p.523 of the thread as a new beginner, with beginner's advice: If stuff doesn't work, try a different cable!
     
    (And if other stuff doesn't work, hey... mess with it :) )
     
  11. m-i-c-k-e-y
    Ok why not change your universal charging hub for a powered branded peripheral hub just like mine.
     
    See above.

    I know they have development and delivery issues. But for Android and Portable users this is interesting:
     
    Think a battery operated USB Regen/mini Hub: LightHarmonic's Revive

    Thinking piggybacking my portable USB dac on this.

    No.
    Lhlabs.

    For me.
    Ever.
