need a digital coaxial lead to go from blu-ray payer to my ruby ki amp,any recomendations
I use the amazon basic coax cable from my cd transport to my Hegel amp. I did buy a QED signature coax but prefer the sound of the cheaper amazon cable but I suppose just trust your ears.
Fully agree with the analysis. There is a potential wrinkle ,which the marginally inferior Optical fibre eliminate entirely. .. an earth loop can be formed and hum injected into the amplifier via the external braid. Very few if any coaxial inputs use a pulse transformer..even at the cost of a few cents,and that would eliminate any potential hum.The QED or the Audioquest Forest in the £25 to £35 range are not unreasonable, and those are good quality cables. But they are also probably unnecessary. You could even go as high as £50, though most would agree that this is unnecessary.
A cable, well chosen, in the £10 to £20 range should more than get the job done.
For the right cable, even under £10 is OK.
Keep in mind the range of errors in a digital signal has to be massive to be heard, and since the cable is transmitting digital, it can't effect the highs, lows, or mids because those ranges of sound can't be isolated from what is really just a series of numbers.
If we assume a Sample Rate of 44.1K which is CD quality, then for there to be a HALF SECOND error in the data, that would be about 22 THOUSAND consecutive errors. That is simply not going to happen. Even if the cable gives you a still pretty substantial 1,000 consecutive errors, that is only 0.02 seconds, which you absolute can not hear.
Digital transmission are pretty reliable and chances of 1,000 consecutive errors (0.02 seconds) is next to impossible.
In an optical cable, poor fiber can dim the signal, but at normal lengths that typically not a problem. But Coaxial is a direct wire connection, and the cable length would have to be massive to compromise the integrity of the signal.
The numbers either get through or they don't. And a vast majority of time even with low cost cable, the numbers to get through with surprisingly high accuracy.
I don't see how people can claim better bass or clearer Treble or any other frequency related characteristic from one Digital Cable over another. Audio Frequencies are not going through the cable, only a representation of numbers. And, as I said, either the numbers get through or they don't, and a massively vast majority of time the numbers get through absolutely error free. Typically data transmission or interpretation errors would only occur at extremely long cable lengths.
Now with better cable there is a durability aspect as well as general aesthetics. But I would have no problem with, as an example, the Sub-£10 KableDirekt cable. Especially on a generally consumer grade system. On premium or high cost (relatively speaking) system, I might be tempted by more expensive cables but mostly for durability and aesthetics.
However, if I had a fairly decent consumer grade system, I would more likely go with the Fisual Havana or the Van Damme Premium Coaxial. These are both under £20, just under. But quality cable with quality connectors. £20 isn't going to break the Bank for most people.

The Van Damme makes it clear that it is using 75 ohm Transmission Grade Cable. This is a grade of cable that is typically used for Radio Frequency transmission. This would be TV antenna cable or Cable TV cable, or point-to-point high frequency transmissions.
Just make sure you get the length you need. For example, the Van Damme is 50cm or about 20 inches. If that works for you, fine, and I suspect the same Van Damme Cable is available in other length, you just need to search them out.

Both available in a wide range of lengths and in assorted color choices. £13 sand £16 for 1 meter. That is probably your best value.
The numbers either get through or they don't, and generally speaking, even with modest cable ... the numbers get through.

Hello, old friend!You are correct ...however... any Signal Level Wire can have this problem, but, realistically, how often does it happen? MILLIONS of audio systems world wide us coaxial cable, typically not for digital though, and have no problem.
But you are correct, it is a potential problem that is eliminated with Optical Cable.
True he may have his cable by now, but he is not the only person reading the thread and is not the only person with this problem. Others can be helped by the answers.Think he’ll have his cable by now. This thread is 2 year old.
