Advice for belden RCA Cable to use?

[Jeff M.]

My recommendation would be to buy assembled cables. I like Canare LV-61S because it is flexible. The Canare crimped connectors are nice. If you want to stick with Belden, the 1505F also uses a stranded center conductor.

Canare LV-61S

Thanks for the info. Jeff

Why would you want to match brands of cable?

I have no idea who you would like me to answer your post about using the same cable brand and no need to. Just wondering Has Amirm tested this theory out about cable matching? I would be interested in see what his test and thoughts are after the whole procedure?

There is no theory of cable matching.

The music you listen to was recorded in a music studio where there are hundreds of cables from multiple vendors.

 

[Speedskater]

I don't think that Amirm has enough time to test every (or even some) of the nonsense ideas that equipment manufactures and audiophiles come up with.

Here is one for speaker cable.

Audioquest GO-4 Speaker Cable Review

This is a review and detailed measurements of the AudioQuest GO-4 speaker cable. It is on kind loan from a member and costs about US $599. The attached dongle is a 72 volt battery supply that feeds an unterminated wire the length of the cable. Different terminations can be ordered. Here are...

AudioQuest Wind High-end Cable Review

This is a review and detailed measurements of the AudioQuest Wind RCA "PSS Silver" cable. The sample I have was kindly donated by a member and costs US $2,300 in the 1 meter configuration. No, that is not a typo. It is over two thousand dollars for a pair. The cable comes in a rather cheap...

AudioQuest Victoria Audio Cable with DBS Review

This is a review and detailed measurements of the AudioQuest Victoria Audio interconnect with "dielectric-bias system" (DBS). It is kindly loaned to me by a member and costs US $299. The configuration I received is unusual in the way it has RCA connector at one end and some kind of 5-pin at...

You can do what you want, but at audio frequencies for RCA get cheap coax RG58, RG59 or RG6 and go about your business. There isn't anything going on here.

These Monoprice cables look pretty nice, use RG59 and will do just fine for a really nice low price.

Wow lots to digest in my brain. . What am getting is at the end of the day cable is cable no matter how you look at it. Some cost more than others and it either works or it doesn’t . Like Hdmi cables it’s all 1’s and zero’s no matter what kinda cable design you come up with. Thanks everyone. I got it. Thanks for everyone’s help on this topic.

It's a bit more nuanced than that for some situations, but that covers most of it.

I use premade cables for unbalanced line level audio connections because, as Amir has proven, even the cheapest such cables are more than adequate for that job. For electric guitar, I use thin Belden 8218 coax because it mates up properly with the solderless TS plugs I love for that application, but its 20pF/foot capacitance would also make it a good choice for turntable connections.

What connectors are you using with the Belden 8218?

They're 1/4" TS phone plugs -- not the RCA type needed for home stereo gear. I got them many years ago -- nowadays they're only available as a kit: https://www.wildepickups.com/collec...ucts/cable-plugs-set-1?variant=32638205067326

The point of non-equilibrium is
The ground area should be large enough to create low resistance
Appears as a shield on the cable

This understanding cannot be vague

Resistance is a non-issue for line-level RCA-to-RCA audio connections -- an ohm or two makes no difference. Shunt capacitance can be problematic, but only for relatively high impedance, low level circuits like turntable connections.

Interesting and good point because the big wire companys think an ohm or 2 do make a difference even with RCA Audio Connections .

An ohm or two in what way?

 

[Speedskater]

Resistance of the central conductor is a non-issue.
But end-to-end resistance of the shield is an issue.
High resistance may increase Common Impedance Coupling Noise currents.

High resistance may increase Common Impedance Coupling Noise currents.

So, at what sort of shield resistance number would this become an issue given audio frequencies and typical unbalanced audio gear connection impedances?

 

[Speedskater]

Well the better coax cables have a shield resistance under 10 Ohms per 1000 feet.
Bill Whitlock (retired Jensen Transformers) suggests 2.5 Ohms per 1000 feet (about 14AWG).

 

[Bruce Morgen]

Well the better coax cables have a shield resistance under 10 Ohms per 1000 feet.

IOW, for a typical 1-3 meter RCA-RCA cable in a line level audio application, it's a non-issue even for coax with 2-3 times that resistance number per unit length.

 

[Palladium]

Spending so much effort for a cable carrying frequencies and at lengths that are magnitudes way below RF...Really?
