So part 2 on this. I had all the items hooked up to my Macbook. Played with it for over an hour with ZERO issues. Last night I used my Ipad Air 2 as the source and I lost connection two times in an hour. While that's better than the Iphone it's still an issue. Now I am at at crossroad. Maybe I should send it in the Chord to check out. Kind of irritated as I thought the issue was the older phone connection.
I think it is highly unlikely that Chord will find anything wrong with that unit. This is typical of the strange trouble you get into transmitting digital signals.
Somehow you have packet loss between your units. After a period of time of packet loss the error correction suffers overload and breaks the connection.
The two principal reasons for packet loss are too much RF picked up in the cables degrading the S/N of the stream. The other is impedance miss match at cable connections and between units. This causes packet loss by reflections where there is an impedance change. It only takes a 15 to 20 ohm miss match for this to occur. Very slight cable damage can cause this also, even if a meter test shows continuity.
RF can come from light dimmers, motors and above all these days LED light bulbs. Modern homes are increasingly awash in RF noise.
To reduce RF, you could rap your interconnecting cables in aluminum foil and see what happens.
The next step would be to change all cables and connectors.
You have classic symptoms of excess data package loss.
Do you wonder turntable sales keep going up?
This is my latest saga with digital interconnection.
And that gives me another thought. Your digital signal may be degraded before it even gets to your iPhone or Macbook. Go on DSL Reports and look at the speed, quality and buffer bloat at your phone.
With your problem the odds are overwhelming the problem is external to your devices.
