How flexible is this cable?
Robert C
on Aug 23, 2017
BEST ANSWER: Robert it's hard to quantify how flexible this cable is. I can easily coil the cable twice to a six inch diameter (3 in radius), I wouldn't recommend bending the cable much more. The cable seems high quality with excellent connectors.

High quality but the cable head is rather long. Make sure you have an extra inch to plug it in when your space is tight

This cable is very flexible but it is also sturdy. You can bend it probably just not at a 90 degree angle.

It is fairly flexible. You can make a 2in diameter 180 before you start to feel resistance.

Is this connector any looser/more flexible than the #2683 cable? I have a 2683 and it's WAY too tight - it makes me fearful of damage every time I make the connection. This one more forgiving?

BEST ANSWER: Twisting the collar down loosens the connection, once it’s on, tighten the collar back up.

Are these connectors removable/reusable? I noticed a flathead set screw on them, and am wondering if it would be possible to shorten them to an exact length for a custom installation I'm doing.

would these cables be suitable for connecting analog sources to my amp, as well as running audio to and from my computer? i have things set up for doing analog to digital transfers, be it from vinyl, cassette, 8-track or whatever... would this be the cable to go with, or is there a better option available here that i should be looking at?

nice cables, but be aware that connectors are fat and long
These are nice beefy cables, but the rca connectors are too fat for some jacks that are spaced closely together like the jacks on my Dual 1219 turntable. You may also have problems with the length of the connector if you don't have a lot of clearance behind your jacks.

Works as expected, excellent build quality
Bought this to replace a makeshift cable I'd been using for my subwoofer for years. The build quality is top notch, the braided cable is nice, and it works as expected.

Unmarked for separation
I bought 2x 25 foot Onix Series cables. They appear to be of very good quality with 1 serious omission. There is no distinguishing feature between the right and left cables--they appear to be identical. I didn't realize this until after running the cable behind and under a bunch of furniture. There is no way to determine which is right and which is left by looking at the cable ends so I have to undo the run and mark the cable ends myself--an unnecessary inconvenience.

Hands down the best Digital Coax I have ever used. Looks like a $100 cable for $7.10. Love that the heads screw over the crimp for a tight secure connection. Tempted to buy a bunch more to have for the future.
