RCA versus XLR interconnects

For what it’s worth, MacIntosh technical advisor said he would use XLR over RCA all the time regardless of the length because of RF interference. 

"It depends" is the most accurate thing I have seen posted yet. 

It depends on if you have any interference problem. Few actually do. 

It depends if you have some ground loop fault you are not fixing and want to band aid. 

It depends on the quality of the execution of the drivers and receivers. Some good, some terrible. 

It depends on how much money the salesman wants to make.

It depends if you have a new Purify/Hypex ilk amp that is by definition a balanced architecture.  Best if the source is also balanced.  Many modern DACs are.  ( and many the DAC is, but the IV is not and a balanced driver is just hung onto it. )

It depends if you feel the need for bragging rights over actual performance.  Even Chord is se at the Qutest level. Balanced is not necessary for most systems according to Mr. Watts. 

If you need boutique cables, It depends if you are a snake oil believer and feel the need to find some magic that Mogami,  Cardas, Belden, or the studios who use miles of said cable do not know. 

If making your own cables, how easy to assemble Cannon vs Amphenol vs various others can be a royal pain.  I am not really a fan of XLR connectors. At audio frequencies, terminal strips can work just fine and are widely used in the field. 

I promised to report back, and here's the reply from Eversolo:

Question:

I have an Eversolo DMP-A6 DAC/Streamer.

It has XLR outputs, but I want to know whether the circuitry inside the unit is fully deferential?  In other words, two completely identical circuits out of phase to minimize distortion

Answer:

Regarding the issue, the answer is yes.

-----------------

Seems like this budget $850 DAC/Streamer has a full differential circuitry but Jay Iyagi (https://www.youtube.com/watch?v=ESZxMDxapm0) suggests it's Op-amp. One can only verify by opening the unit up which I'm not going to do so since it's under warranty.

You don’t seem to understand balanced differential circuits, which commonly use operational amplifiers. It is not as simple as "two completely identical circuits out of phase to minimize distortion" as you seem to believe.

One can only verify by opening the unit up which I'm not going to do ...

The schematic would be just as helpful.

You’re probably right but I really don’t want to get too much into it either. 
 

If I have a decent system and tried my best to maximize it (without spending too much time), that’s good enough for me. Rest is for the forum community. Someone may find these posts helpful.
