Old phones as streaming sources

The iPhone 5 was known to have a very good dac built in. Just as the play station 1 was known to be a very good cd player. 

@audioguy85  Good for what they are maybe, but not good compared to anything designed specifically for audio.  C’mon man. 

Better off using an old smart phone for a dedicated wireless control of a designed "streamer.'

It just needs to be on the same network.

@bruce19 you recruited a lot of single samples united by a culture of expectation bias x rejection of scientific process. 
There are ways to tell if an iPhone is an audibly inferior streamer. No one who responded has done the required steps to make the aforementioned claims of inferiority, so far as this thread reads. That would require an understanding of experimental design, basic statistics, and a fair amount of time/effort.

I totally understand buyers not being down for doing that! What I tend to scratch my head over is how some folks pay manufacturers (who avoid said due diligence) so much for devices that aren’t verifiably (audibly) different. To each their own.

I just use the old phone as the remote for a headless streamer. Personal preference based on nothing pretending to be a meaningful, broadly applicable test 😉

@benanders  Speak for yourself.  Plenty of us have heard big improvements moving up to streamers from Aurender, Innuos, etc.  Maybe it’s time you tried something better than your Raspberry Pi and see/hear for yourself. 

'I have found  that when I remove the sim card and shut off blue tooth and wire the phone to a dac with an appropriate USB adapter cable, my old iphone 6s makes a pretty good streamer. Just wondering what others experiance has been. It is a really economical way to source digital to a 2nd or 3rd system.'

Good on you mate. My experience is yours. I'm using my 2 old Samsung S3 including a Cambridge XS and a Violectric Chronos DAC for on the fly listening. I am listening as well with the Samsung Galaxys Tab S 2, in this case going into integrated amps with USB 2.0. For this, I have a (now very hard to find) docking station where I connect the USB A-B cable.

In addition, I have downloaded the USB Audio Player Pro app, running all locally stored music files and Quobuz. You would pay a small amount for the USB Player Pro app and you can use it for all your android gear, paying only once. It is this app which makes a big difference, IMO.

To my ears and in my system and listening environement, the above solution is more than decent and inexpensive.

For iOS, instead of USB Audio Player Pro it could be the TEAC HR Audio Player app.
