Android phones and USB DACs - Page 262

post #3916 of 5430

Yeah got the DAC from ebay.

The external battery is a power bank that I got locally. You can use any power bank to your liking as long as it outputs 5V DC. Searching ebay for "power bank" should give plenty to choose from.

Moto G

 

A few weeks ago I posted my experience of trying this very popular phone with various dacs ( see post 3703 ). Basically it did not work ( properly ). However the phone was updated to KitKat 4.4.2 yesterday and I have been checking it out. It's a case of good and bad news. First the good - the phone now works very well with most of my dacs - I am listening to it now through my Stereolink dac and quality is excellent.

The bad news is that it will now not read a flash drive attached via USB OTG ( it worked fine under 4.3 ). This has been confirmed by a post on the XDA forum - ( I am using the Bubble UPnP app to access files over my network ). There are some apps which allow access to files on an attached drive but from what I can see, none of them are very satisfactory as I found I could not use any of my normal media player apps, because these cannot access the files directly. So the update is a bit of a mixed blessing !

I suppose one way round this would be to use a wifi enabled drive or wireless card reader but I have not used these devices myself.

Anyway, I hope this update on the update helps anyone who may be considering a purchase of a Moto G !

Moto G

 

Realised today that my phone was not ringing when calls or texts were received. Took me a few mins, after checking all my settings, to realise that it was still operating as if the dac was attached ! So looks as if it may be necessary to reboot the phone after a listening session via dac ( if you want the phone to ring ) !

Interesting, got a Moto G for the mother in-law over the weekend and this didn't happen when I tried out USB audio. Also, unlike the earlier commentary on USB audio and the Moto G it worked fine for me even on the 4.3 OS version (with Nova Tiny M, HiFimeDIY Android USB DAC and HeadAmp Pico).

I have the Moto G aswell, not rooted and updated to stock KitKat.

 

I am interested in getting a budget DAC like the Nova Tiny M or HiFimeDIY Android USB DAC. However becasue of the phones storage being constrained to less than 5GB, I would like to know if the either of you fellas can verify that the Moto G running KitKat will allow USB audio output with streaming services like Spotify and Google Play Music, or native apps like Youtube and the Chrome browser ?

 

I find the Moto G a great phone for the money, however the headphone DAC to be far, far inferior to my previous phones' on board DAC (a HP Pre3 -> Spotify high quality -> homebrew audio EQ app -> Blox M2C earbuds), and so may reluctantly revert to the Pre3 should a solution (streamed audio through external DAC) prove too difficult to attain.

Yes, USB audio works with streaming services.
post #3924 of 5430
Many thanks for verifying that NZtechfreak. I am delighted and excited by the notion that such a budget priced phone will enable the penny pinchers amongst us to enjoy some half decent sound quality. Am looking forward to hearing the HiFimeDIY coupled with the Moto G.

How much quicker does the battery drain when using USB audio out for a DAC and then amp? Would it drain slower if we just used a line out for an amp and skip the USB audio for DAC?

One hour of listening drains less than 3% of my SGS3's battery, with the screen brightness at max but I basically set it to play one album then the screen switches on only when I switch to another album after that. Also, the DAC in my headphone amplifier (Meier Cantate.2) is completely powered by the amp itselft, but it still takes a current off the USB (and in this case, the SGS3) to light up the USB input indicator lamp on the amp.

I see. Do most portable DACs draw power off the amp and not the source like other desktop DACs?

It depends on each DAC. Some desktop DACs can draw from the USB to power the whole DAC (like the NuForce UDAC), some will use USB power to power some components like the USB receiver chip and maybe also the DAC (like my Superpro707, which is louder when using USB or a different power supply, presumably because using USB means it gets the DAC and receiver power off the USB and the analogue output gets all the power from the PSU). Similarly, some portable DAC-Amps might power the DAC and receiver chip using USB, or use the battery for everything. Some Ibasso units have a switch for battery and USB, or to enable and disable cahrging, but I am not sure if they work on the entire device or just the amp section, so best ask in the threads for them. If they work on a USB port that doesn't charge them, then that means the computer outputs data but not enough power through that USB port, ergo an Android with the right hardware and software will likely work.

 

Fiio E18 works the other way around - it can actually charge your Android.

My current setup is S3---UAPP 1.05----Dragonfly---Westone3

Which volume control would I be better off with hardware of software if I want to add volume via the mixer tab?
