The Importance of the Digital Cable


Good Sunday evening dear friends,

This point of discussion has been on my mind of late, as I have listened carefully to the results. This is a bold statement and discussed ad nauseam here I am sure, though I feel others may be encouraged to explore this more deeply as we share our experiences here.

I’ve had several digital cables, ranging from several coax, to toslink. I have not yet tried a dedicated AES/EBU XLR.

Listening to the Denafrips Pontus, a ladder DAC, fed from an Oppo UDP-205 as transport, I was compelled to try a few different cables, because the results were not as good as expected. I played a few albums; XTC ‘Nonesuch’ - a rather hot recording from the 90’s but very interesting and politically out front. Then an Everett Harp CD that highlights his wonderful sax playing. Then Robben Ford and The Blue Line, the album being ‘handful of Blues’.After that some Arjit Singh, and Tarkan (Turkish music).
The cables running from the DAC to the Pre/amp are Transparent Ultra XL (original). I like these cables because they have a very natural organic sound. They do lack some of the detail up top of some of the best in class and perhaps are a less exciting that some, but over all I love the naturalness, slight warmth in mid-bass, scale and soundstage of their sound.
But things didn’t sound quite right. I can always tell when something isn’t quite right, because it’s harder for me to get involved in the music. Some of the quieter words were too vague, and there was just a general fuzziness and vagueness overall. The soundstage was flatter and resolution of detail was lacking. The Pontus as you know, is a very good DAC, so I knew something was off.

I had the Canare digital cable in place, and decided to switch it out for my Black Cat Veloce. Wow! The sound transformed. Now the DAC truly shined. All the detail returned. The sound was certain and clear. The soundstage was very wide and the vagueness replaced with clarity. The music was now exciting and involving.

This begs the question, how can a digital cable make such a difference? After all, it is transporting a digital binary signal?
Please share your experiences.

Thanks for clarifying Saleh. Yes, I believe I get it -  that the zero / one is an expression of on off for electrical signal, where certain amplitude is represented as a binary, which is in actuality an electrical signal. So, say ten zeros and five ones in a specific on/off configuration represents a certain analogue signal. Thats a gross simplification but is that what is correct?
5 volts

what a nice thing to upgrade that cable for you - class act ! 

I think the bnc connection should be the standard for SP-DIF….

I use both Audioquest and Nordost - they are night and day different, both w strengths. Tastes vary, thank God not everybody likes Talisker

Reflected trash is very real. Dealing with it is one reason why your gps satellite…works..

Sounds like the OP is on a wonderful voyage..
I'm no expert myself but as a simplification, yes )
Digital cables do have an great impact. Even ethernet if you were streaming, which is even more strange and I can't explain it to myself yet. Those network data packets are supposed to check for errors. But with a revealing system, you could clearly do what a proper ethernet cable like AQ diamond does. Even if upgrading from another lower level AQ ethernet cable. I was a skeptic till i heard myself!

I am considering audioquest and nordost for a 2 channel setup I’m looking into. Are you talking about just digital cables of the two or do you have them as speaker and power cords as well? Could you tell me the differences between them you have found?
