RCA to RCA versus RCA to XLR

I try to explain thing simply.

Thanks for the simple explanation, I'll try to explain as simply as I can why you are not correct. If you connect ground to pin 3 then it will be inverted at the input and there will be some benefit of the balanced common mode rejection (summing of inverted interference with signal interference). In addition to this the ground signal will see the input impedance which will vastly reduce the amount of current flowing through it... current flowing through ground is the definition of a ground loop.

I’m not disagreeing with you, I’m saying YOUR way has no benefit to the TUNER, it can’t it is a single ended RCA going to the pre amp not from it. Your way may reduce noise in the cable via the shielding but not by inverting the signal. Doesn’t it have to terminate and then compare to cancel the outside noise, if there is a problem with that?

I’m just an old mechanic I’m always open to being taught by those MUCH wiser than me.. I welcome your experience pounding it through my thick head.. :-)

Second (ly) I’m pretty sure its a 110vac unit. It will have a difference in voltage vs the 120 vac preamp it will have noise. I was adding the ability to put the ground loop eliminator on either end of the run.. That was the biggest thing for me.. The weave addressed a great way to reduce noise without shielded cable.. Your way has it. AGAIN shielded cable gives way to certain SQ issues I can eliminate differently..

Is my way wrong? OR is there a bit of "different" thinking going on. Teach me.. :-) I’m ALL EARS.. It’s the second day of the week I’m ready for school.

With great respect and regards..

I don't think their would be any benefit to doing this. This would be a good question for Ralph to answer.

 is there a bit of "different" thinking going on.

Yep, there's always more than one way to skin a cat... I was just addressing the comments saying there there was no benefit going RCA to XLR. If you have no issues with RF, ground noise etc. then RCA in most cases is the way to go. With ground loops there's a specific problem where current flows between grounds on different circuits, it just so happens that RCA to XLR stops this... it wasn't even the primary reason for balanced interconnects as far as I know.
For all I know a ground loop eliminator might work great, there are always options out there.

What about shielding on cable, are you a fan? I’ve found that shielding in the real world is a God sent. BUT in the stereo world it can really dummy up the sound, I mean really mess with the clarity and SQ.

I’ve found some shielding in my world was a robber of just about EVERY audiophile term ever invented. Then small separate woven stranded types of cable (helix) work wonders in SQ improvement and noise floor reduction. 6 years for me..

Ribbon cable and flat wire cable construction are pretty amazing thing too. Zero noise issues.. HERE..

There was a truck rout right next to my home. Trucks with CBs and CHPs with Ham. The rout was changed 15 years ago and CHP use a different type of radio now, so. NO NOISE.. Better cabling.. :-) Things I’ve learned HERE. 40 year now.

I think sun spot are through the roof too. Weird crap going on here the last two, three weeks. (X-Files theme song)
