Old phones as streaming sources

@lanx0003 Invested a bit more time and watched this 25 minute video with citations about the nature and measurement of jitter.

Leads me to believe it is not that big of an issue. Which, taken with the info discussed above casts some real doubt in my mind about how important the streamer is relative to the dac.

In other words it does not appear to me that there are strong technical reasons that a modest streamer such as a phone can't produce good audio if run through a quality dac...and that is what my ears have been telling me. Now in the interest of full disclosure and fairness I am 71 and have tested my hearing and know it it, at best extends to 11 khz. Amir points out that perception of jitter is most easily perceived in the frequencies closer to 20 khz. So maybe younger listeners could be more sensitive. 

Thank you for checking it out, OP.  May reach out to Archimago and/or Miller AR for a possible answer.

I hope you will report your findings back here if you do. I'm interested.

I have an S21 with half a terabyte of memory and I put most of my CD's in it as WAV files. Plug that into a Mojo and headphones into that and it makes for a nice little setup.  Sometimes I use it in the car system.

@bruce19  Do tell, what other streamers have you compared to the iPhone?  Frankly, with your self-professed very compromised hearing your credibility on this topic is pretty low from my perspective.
