XLR and DBS (Audioquest)

Maybe it would be helpful to pass along my experience on the question of XLR vs RCA. Firstly if you have a long (say >3M) run then you have no alternative but XLR, as RCA will be too probe to pick up noise. Having said that a poor implementation of balanced circuitry (on which Ralph has expounded at length) will sound worse than any single ended. Be aware that many (if not most) so called balanced circuits are simply front or back ends to single ended circuitry inside the amp or component. Hence my recent experience with my DCS kit actually sounding better single ended, most likely as the balanced connection is going through another step to convert single ended to balanced

However in balanced cables favor the XLR connection technology is way better than RCA, no risk of loose connections or bad grounds -- which even led to me losing a woofer in a pair of Magico V3s once

So what does this boil down to? My rule of thumb logic tree

1) Is your connection >3M then, go balanced
2) Is your equipment (at both ends) true balanced circuitry, then go balanced
3) If 1 and 2 are false then go single ended
4) If 1 is true and 2 is false then move your equipment!

Not too complicated in the end 🤔

Bob, for Atmasphere's comments about insensitivity to XLR cable differences to be applicable, the components being connected, especially the component which is driving the cable, have to meet certain criteria he has described.  His designs meet those criteria, as do some others, but my impression is that the majority of designs that are out there do not.

For his description of those criteria, and for what I consider to be a persuasive proof of his contention, see the first of his posts dated 3-22-2013  in this thread.  Also see my follow-up question later in the thread, and his answer.

Thanks Al, and Folkfreak.
Great information.

I have aq wel w DBS speaker cables and they are fantastic.  I would like to see what happens if I disconnect the DBS however...
