I find that silly pretentious, what is the REAL advantage or even need of that?
Clumsy impractical, just to be "special" or "different" and of course turning a $120 amp into a $899 one.
Same as "carved from a solid block of alumimum chassis" ..... that certainly means it "sounds better", isn´t it?
In any case, if you want to enjoy the full "I use expensive stuff" aura, junk your current Audio equipment and get fully balanced out versions,WHAT are you doing with lower Social Class RCA outputs to begin with?
Using "adapters" (Ugh!!! 💩) is NOT socially acceptable.
I premise that I've absolutely nothing against you, as on the other hand against obviously nobody else here, and I decided to answer you anyway in order to demonstrate "intellectual chivalry" (please note the quotes and the italic style), if you may know what I mean.
Facts are facts, and if 2 things differ in a single even small detail then those 2 things can not provide the same result.
It is impossible.
Otherwise those 2 things would be the same, but they are not, and if they offered the same result then it would be an obvious contradiction of terms.
It is simply impossible.
So, my actual signal cables
[that are not expensive at all, but still XLR just because my power amp (not expensive at all) MUST get a balanced signal]
offer an actual given result in terms of Sound Quality, you know?
Well, if just right now I interpose - moreover without a real reason - a couple of fu**ing adapters between my power amp XLR sockets and whatever you want connectors of my signal cables (not expensive at all), then the result in terms of Sound Quality CAN NOT BE the same, because it would be completely ILLOGICAL!
These are facts.
Indeed, these are incontrovertible facts!
Whether I or anyone else can hear that inevitable difference?
Who can say that?
Who can deny that?
And we’re back to own beliefs, preferences or preconceived ideas.
P. S.: Please note that I care so very much about the integrity of my audio signal (please note that it’s my fu**ing business, since also the system is mine! 🥷) also and especially because my system is not expensive at all and therefore its characteristics in terms of Sound Quality - whatever they are - must be preserved and if possible strengthened, not mortified, if you know what I mean.
End of these games, or at least I really hope in that!

Nope, "sound quality" is a subjective evaluation and not proof of anything since it provides no objective basis for discussion.
You can make hand-waving declarative statements regarding "incontrovertible facts", but it doesn't make them facts. I'm sorry.
You're offering up audiophile dogma as a premise for your stance. It doesn't work that way. I'm sorry again.
Interfacing an unbalanced output to a balanced input is straightforward. That's not to say that it will work 100% of the time. This is electronics after all and weird things can happen. 🙂
But, to associate a reduction/change in "sound quality" to the usage of a simple adaptor is speculative, at best.
DIYaudio.com is, thankfully, an audio forum mostly devoid of this type of discussion.
Cheers,
Dave.

How about the related Sound Quality, then? 🤣
This is a vulgar judgment of those who wanted to "understand" only what he wanted to "understand" and don’t care at all about the opinions of others.
In other words a total intellectual disappointment.
You have no idea what "intellectual chivalry" is, do you? 🙄
Well, I'll reply you no more, neither here nor elsewhere, but: on your way, you! 😉
There's no such thing as "intellectual chivalry." That's just a made-up term so you can feign outrage.
But, feel free to notify the forum moderators about my lack of "intellectual chivalry." 🙂
You can look at my posts on this forum for the last twenty years. I (almost) NEVER talk about my own subjective evaluations or sound quality opinions regarding audio equipment. There's a reason for that.....because it's not relevant.
If you want to talk nuts and bolts about the electronics, then we have a basis for discussion.
But, don't come on here and parade all your subjective evaluation incontrovertible facts in front of me.
Dave.

I dunno... I had to look up chivalry. Intellectual chivalry doesn't sound too bad...
Here's the definition from dictionary.com (highlighting curtesy of Google):
Intellectual knighthood? Sounds special. 🙂

Since it seems that you've interested in LDR preamps please note that on the Forum there is also the following (from the member @zdr) that I have too and that also sounds good, also it with no XLR sockets though. AFAIK
https://www.diyaudio.com/forums/ana...dr-pre-mkii-ldr-volume-control-switching.html
I also add a pic of of S. C. preamp with 2 transformers showing one of the many customized iterations I made over time (even if I no longer use it in my system) related to the volume control driving through a separate non-standard relays board.

Of course each of us hears music according to our particular circumstances - our preferences/conditioning/filters/age etc. etc. but the fact is that it is us homo sapiens that actually listen to music not measuring instruments. I spent most of my working life in construction and I've worked in a few European countries and unlike musical equipment if you don't follow basic rational iron clad construction techniques then you can and do end up with constructing a piece of crap that can and do fall down. When I look at a lot of American home construction I'm not surprised when a strong wind leads to the collapse of the house or using timber construction in places where Termites strut their stuff, where aercrete blocks are unheard of. Right now in France and other parts of Europe houses are going to have to be pulled down because the foundations are insufficient being built on clay which expands and contracts with really wet and dry weather. Totally forseeable and should never have presented a problem. Re. the S/C I was stating an opinion which others could check out or ignore.
So construction and audio equipment are completely different. Audio equipment can measure far from optimum but be enjoyable to listen to aka valves/tubes and distortion but construction is all about iron clad rules - break them and you have a piece of crap instead of a home.
ulogon,
I recognized the Chris Daly PCB immediately, you may have moved on but I'm still enjoying it

I have an issue with the suggestions in the Rane notes for unbalanced phono to balanced XLR
If the source is class 2 (double insulated) and the amp is earthed, the source will be referenced at more or less half the mains supply voltage, and this can be greater than the maximum common mode input voltage of the amp - assuming no transformer
To solve this I ran a single core cable from pin 1 of the XLR to the case of the source - I actually used the shield connection on a phono plug in an unused input on my pre-amp
I tried connecting the screen at both ends, but the screen current caused humming - putting this current down a separate cable solved this
Brian
I saw that one, but they end up putting the (small) current down the screen too, although in parallel with one of the cores
In my case I have TV headphone out (with DVD player etc. connected to TV), karaoke machine and Belkin Soundform as inputs, so the current could be higher than "normal". Feeding this independently made quite a difference

@brig001
Understood. Here in the U.S. that configuration would not be common, but possible.
Note that the Rane reference qualifies this sort of configuration.
Quoting....
"The Last Best Right Way To Do It
If transformer isolation is not an option, special cable assemblies are a last resort. The key here is to prevent the shield currents from flowing into a unit whose grounding scheme creates ground loops (hum) in the audio path (i.e., most audio equipment).
It is true that connecting both ends of the shield is theoretically the best way to interconnect equipment -- though this assumes the interconnected equipment is internally grounded properly. Since most equipment is not internally grounded properly, connecting both ends of the shield is not often practiced, since doing so usually creates noisy interconnections."
So, they're not unaware of possible issues.

@Davey
That's true to a point, but the problem in my case wasn't a ground loop - it's the volt drop on the shield caused by putting current through it
This adds to the output voltage from the source and is seen as an input to the amp
Moving this to a separate piece of wire solved it for me and might help someone else one day
