Roman in a few posts you have made reference to the interesting topic of cable current loading. I'm keenly interested in your findings. |

Glaesemann, there is not a lot to talk about it. My observation showed that practically any cable I trued was benefited from current loading… The more currant cable cares the better is sound. There are many explanations why I have no time now…
We can’t infinitely get current in cable as voltage in the cable whatever it is. We can drop the output impedance only up to a point and increase load impedance up to a point (there are other then rise currant consideration in it). So, the most reasonable solution would be to drive DC current across the cable, the cable that cares AC voltage of signal, or to bias the cable. There is a large array of options how it might be done – here is how I did it in Melquiades.

Still, depends of the topology of the inputs and output stages the different biasing methods and configuration could be used. You might drive currant in and against the AC flow, you can even inject some UHF modulation if you wish – it as all changes sound. To my knowledge no one look at this direction. In fact I very much sick from all cable people – the audio-inhabitants as soon as they discover any more or less wining configuration immediately begin to bake cables for trade and in a season or two the Sound goes to toilet and eventually we - the users - who would like to have specific result from cables are getting instead of Assured Sound only the arrays of random marketing metaphors.
I for example need now a 2M cable and I have no financial or any other restrictions what this cable it might be. I have a specific sonic requirement to this cable and I might approach any manufacture in the world to do it for me. So, what? I am completely disabled not only to get cable but uneven to explore cables because no one sells Sound but they only sell the fucking design concepts… I relay do not see myself with my today’s experience in the field to obtain again a bunch of the cables and to try them all – that is just the very stupid way to do the things.
Why we do not build our cables (any element of audio) in the way how we design bridges? Building bridges we develop precise and predictable characters and we do not do “matching” and “guessing” – we get what we need. Why we do not do it in audio? Where all those empty academics who can’t make a piece of wire with predicable sound? If I am stupid enough and willing to pay $2000-$10000 for an assmply of $5 wire in a fancy $3 jacket then the people who want to sell me should assure me the predictable result – if not, then they ether should pay me to try their cables and educating them how they sound or… fuck them all.
Am I sounding pissed and unreasonable? Perhaps, but it is my attitude nowadays. Anyhow, I am listening the 8th hours of the WHRB Rostropovich’s Orgy and as I feel now any single audio cable manufacture shell hang itself on own stupid cable, preferably the high-current biased cable…
