Android phones and USB DACs - Page 427

post #6391 of 6394

Hi Guys. I'm a long-time head-fi lurker. Firstly, I'd like to thank all of you here who have helped me spend my cash. I'd be considerably richer without you. 

 

Most of my headphone listening is done via a Hisound Studio V, usually with M-audio Q40s or Superlux HD681 Evo's (until the left channel developed problems). I'm very intrigued by this Android-> USB DAC 'craze', so decided to try it out. 

 

I recently bought a ZTE Nubia Z7 Max. I have an unused Behringer UCA202 lying around, so I hooked them up and got it working without any problems. I tested it using the Kenwood music control app, the Onkyo HF player and the stock music player. All of these worked fine. The Onkyo HF player has a nice 11-band graphics EQ if you like that kind of thing.

 

I was pretty pleased to have got this working so easily, but the UCA202 seems like a POS. The headphone out on it is especially bad. I struggled to get a decent volume out of my Q40's even at max volume. The headphone out on my phone sounded better. I then hooked the line-out of the UCA202 into my Fanmusic mk2 headphone amp. Whilst far from mind-blowing, this sounded a lot better. Finally I did a quick A/B test with the phone/uca202 and the dugood hdap-01 both plugged into a nad c355bee amp, powering some monitor audio bronze bookshelf speakers. The hdap-01 wiped the floor with the uca202, which should really be expected considering the price difference. 

 

If anyone's on the look-out for a phone to feed a usb dac and like bargain-hunting in China, check out the ZTE Nubia. I has a nice screen, pretty good camera and the all-important smooth swipe action. I picked mine up for under 250 british pounds on aliexpress, with shipping in under a week.

That's because that unit relies on USB power that they expect would come from a full-size computer. A DAC-HPamp that runs  on its own power supply or battery, so long as it needs no drivers, would work no worse with a compatible Android (or iOS) device. Note though that just because it has a PSU or battery does not automatically mean that it runs every chip and from either - in some cases at the very least the USB receiver chip is run from USB power (which acts as its trigger to prioritize USB input), in others the DAC section is run off USB while the headphone amp section is what runs off its own PSU or battery.

I guess if you pay $60 you'll have accept a little bit of a crook look. I'd rather hit the kick a bit and do a little better. We have choices to fit our needs.

Does anyone know if the iFi Nano idsd works with OTG and a Note 3?
