6LF: RCA/RCA or XLR/RCA. AUDIBLE DIFFERENCE? Really?


my new to me Sony SACD/CD player xa5400ES has optional Male XLR out or Female RCA out.

6LF: RCA/RCA or XLR/RCA. AUDIBLE DIFFERENCE? Really?

INTO RCA female (McIntosh mx110z tube tuner/preamp). (neither my preamp or Cayin amp have XLR IN).

Now: 6 lf, 6 nines copper locking rca connectors.

peeled two of these component cables apart for 3 pairs of interconnects

..............................................................

I am starting DOUBTFUL, but having zero XLR experience, Asking:

I understand avoiding interference for pro use/long runs ...

I don’t have any interference with the cheapest rca cables.

HOW? WHY? could XLR SOUND BETTER????

ebm,

I nave zero noise, and rca/rca has excellent dynamics.

Everyone/Anyone ....

I have read an awful lot of on the forum about 'Balanced', but not much response when asking WHY BETTER?

Post removed 

I have a spare pair of matching cables, 6 nines copper, locking RCA's both ends. they sound terrific now.

I'm gonna change the connectors on one end to XLR female, leaving locking RCA's on the other end. I've got some Cardas silver solder.

That will give me direct comparisons: two pairs of identical cable construction and length, only variable: xlr or rca out.

noise

happily, my entire system is dead quiet, tubes and all, pleasantly surprised every time I turn it on. bought used mx110z had a very slight hum when volume was juiced past half (more than needed, but still ....). Gone after Audio Classics overhauled it.

Prior McIntosh SS Preamp C28 had a slight hum. McIntosh overhauled it, declared it up to specs, came back still very slight hum using low level inputs only. I changed the ground connection inside, gone. Sold it to get back to tubes.

Occasionally I hear a very faint hum, oh no, then I realize I left a fluorescent light fixture on, it's expensive high class noise free ballast has a very faint hum. OFF, gone. Whew! 

My closest audiophile friend with a wonderful sounding system lives with tube amps with a slight hum. I've offered to go thru and isolate the source, but he has lived with slight hum, had them fixed by the maker, ok for a short time, it came back. I couldn't live like that. My old Fisher Mono Blocks, 80z made it 1958, are dead quiet. I used to forget to turn them off frequently.

I've never had any noise except many years ago, when listening to Onkyo's 1st receiver with TV band tuner, it picked up a CB radio occasionally. Problem went away by itself, perhaps someone moved. And recent tonearm, exposed silk covered litz wire got worn to bare wire, a faint buzz, killed it with new wire. 

 

 

On my ESOTERIC 03XD XLR is much better more dynamic and quieter as well.Good luck.

Long runs and more gain. Important if you need it otherwise the extra gain can cause audible noise, so not always a plus.
