Razlike med kabli resnične ali samo nateg?

Slab kabel slaba zaščita in potem se zgodi to kar se zgodi. PVC prozorni ovitek počasi se strdi in zrak pride do žic katere oksidirajo in tako naprej. Več kot 10 let imam iste "stare" dobre kable in ni nič narobe sonično. Delajo enako dobro kot na začetku. Je pa res da so z naravnnimi materijali zaščiteni kar pomaga pri ohranjevanju samega provodnika.
Srebro ??? Kašne kvalitete in obdelave veliko pomeni. Posrebreni so danes manj al več vsi kabli. Kako in z kašnim srebrom je pa vprašanje.

Kabla ne mislim takoj zamenjat ampak počasi začenjam zbirat informacije.

Dobro desetletje sem poslušal glasbo - "bolj na glas" - kvaliteta ni bila "pomembna". Sedaj sestavljam sistem na novo, amp in zvočniki so že ter v.d.h skyline zvočniški kabli. Ob priliki sledita še cd player in povezovalni kabel.

Preko ebay.de gledam poleg Sonyjevih espiritov tudi Technicse serije 7 in 9. Ko bo ugodna ponudba, bo nekaj priromalo, da nadomesti odstoječi player.

Hvala vam za nasvete.

Kabli se "zvočno starajo" eni več drugi manj...
Vse je odvisno od izolacijskih materialov in njenih "lastnosti",ki pa se z leti zelo spreminjajo,ker so to ponavadi "sintetični" materiali,ki so zelo občutljivi na UVsvetlobo,ozon in še marsi kaj...Čeprav so sintetični materiali težko razgradljivi pa se njihove izolacijske sposobnosti z leti zelo spreminjajo...
Omenjeni "karbon" je tudi zelo občutljiv na staranje še prav posebaj prve verzije Van den Hula,ki je imel slab zunaji oplet...Sintetični karbon je zelo občutljiv na UV žarke...Njegov brat grafit pa je večen ... Zato kabli ,ki imajo za zasnovo grafit se manj starajo...
Če sedaj upoštevamo spremenjene lastnosti izolacije in dodamo še spremembe geometrije,ki tudi nastane s popuščanjem materiala je zvočna sprememba neizbežna !!!
Potem pa so še tukaj "prevodniki",ki z oksidacijo spreminjajo svoje lastnosti...
Vendar to se dogaja samo pri cenenih kablih ...
Sodobni LCOFC vodniki vsebujejo tako majhen procent primesi ,da je oksidacija zanemarljiva...Če je še kvalitetno in enakomerno posreberena ali še dodatno prevelečena z Berilijem,rodijem in še čim drugim ,ki so tisočletni materiali se "električne" lastnosti ne spremenijo v cca 15-20 letih !!!!!

Naletel sem na zelo zanimiv site (avtor Arthur Salvatore), kjer se avtor dotakne tudi problematike kablov v povezavi z audio industrijo oz. audio revijami.... Spodaj pripenjam nekaj zanimivih izsekov zanima me pa če kdo ve:
- katere firme, ki prodajajo audio kable nimajo lastne proizvodnje (sodeč po besedah avtorja je takšnih sleparjev, ki zaračunavajo 1000% marže precej)?
- kdo so dobavitelji tem prodajalnam, ki samo tržijo audio kable? Očitno je mogoče do ultra fancy kablov priti precej ceneje kot to predstavljajo audio revije

Tole je site:
http://www.high-endaudio.com/magaz.html

Tole pa izseki:
There is no subject or component category that has been as revealing of the magazines', and their reviewers', (lack of) integrity as audio cables. In less than 25 years audio cables have gone from an afterthought to a major investment in most systems. The prices have also skyrocketed from less than $ 50 to tens of thousands for the (so-called) "best".
Simultaneously, the cable companies have slowly become some of the largest advertisers in almost every audio magazine. In return, these magazines have published 'reviews', and "recommendations", of the "better known" (most heavily advertised) brands and models. Meanwhile...
Virtually nothing else has been printed about audio cables by them. So, one may ask, where is the problem with the magazines' self-proclaimed integrity? They're honest and open, aren't they?
I used the expression "cable companies" in the above paragraph. Did you think it was an oversight on my part that I didn't use the word "manufacturer" instead? After all, that is the word that all the magazines (and the 'reviewers') use, or at least imply. I didn't use it for a very good reason: It is not true. What is the truth?
Virtually every cable company you have ever heard of (or ever will hear of) does NOT make its own cables.
Are you surprised, or even shocked by this statement? Well, I was too, and remember, I was in the audio business for more than 20 years. In fact, I even discovered (from the actual manufacturers) that many cable companies don't even design their own cables. They simply choose among different designs, materials, colors, terminations and the overall volume (total length). Then they are quoted a price, and that's it. Some companies may perform some custom terminations at their "factory", but that's all the "manufacturing" they'll ever do.
The magazines (and their 'reviewers') know all of this of course, but they make damn sure that their readers don't.
Why do they suppress such basic information from their own subscribers?
The magazines realize that the word "Manufacturer" implies huge initial expenditures and investments of time and money, plus true size and importance. Simply ordering 50 or 100 pairs of cable from some large, 50-year old manufacturing plant, at their normal volume discount, doesn't even begin to convey the same image of scale, the same sense of expertise and commitment, or earn the same amount of respect or prestige, does it? Most importantly, a consumer, knowing this underlying reality, would be hesitant to pay the now outlandish prices on these cables.
It's obvious that anyone with some money to invest can do the same thing. Magazines don't want their readers to think that any of their advertisers are just "anyone". The only serious monetary "investments" any of these cable companies will ever make is in "marketing" their products.
As we enter this new decade, it is no longer even slightly surprising to see cables for thousands of dollars, even for short lengths. Some cables are now above $ 20,000 a pair. Only around 20 years ago, the most expensive cables were all $ 200 or less, and some of them even used pure silver. So what has happened?
Well, the cable companies discovered that some customers were prepared to pay more, a lot more. Even more important, they also found out that the magazines never questioned, let alone challenged, the prices they charged; $ 500, $ 1,000, $ 5,000, $ 10,000 etc. (Retailers weren't complaining either with this new development; A $ 200 sale became a $ 5,000 sale!)
No one, not even those cable companies that didn't advertise, was ever asked to justify their prices. It didn't matter what the cable was made of, or its build quality, or its terminations etc. No questions asked. Why?
The magazines are afraid, almost to the point of terror, that the readers/customers will discover that the markups on cables are now very similar to those on "illegal drugs", over 1,000%! The outraged reader may even lose his Audio Faith. (See the next subject below.)
The magazines' "don't ask, don't tell" policy doesn't stop there. For further protection, they will not even compare any of the (now rare) reasonably priced cables to any of the high-priced models, unless they already know that they are inferior (a "fix"). Why?
The magazines know that if even one low-priced cable is better, the entire myth that all high-quality cables must also be high-priced will be shattered, permanently.
The magazines have never compromised their "total package of protection" for the cable companies. That's why there exists today a "reference speaker cable", with "rave reviews", from a very well known "manufacturer", which retails at $ 9,500 for an 8' pair, while his own cost is less than $ 100 from the real cable manufacturer, and he can still "sleep like a baby". (Yes, under $ 100 dollars, including terminations!)

zakaj so tisti dragi kabli, recimo norodost odin tako dragi je res tezko razumeti. notri je sicer kar nekaj material, ki gotovo ni posebej drag. material vsi izdelovalci kablov nekje kupijo, ker drugace na gre, sami gotovo ne vlecejo zic take ali drugacne cistoce, jih ne 'plastificirajo' v izolacijo, ker se jim to prav gotovo nebi splacalo. tako najbrz vecina izdelovalcev iz zbranih/kupljenih materialov rocno sestavljajo kable po edinstveni geometriji, kakor vsak zase trdi. ce tako gledas, nihce ne dela svojih kablov ampak po drugi strani kje pa lahko kupimo enak kabel za 100 evrov?

npr elrodovi stari statementi, ki so bili 2500 usd so konstrukcijsko zelo enostavni. gre za stiri bakrene trakove (ribbone) siroke cca 40 mm in debele cca 0,3 mm, po dva za + in dva za - za ozemljitev pa je uporabljena 'navadna' licnata zica. vsaka zila je vstavljena v ohlapno izolacijo, najbrz teflonsko in nato se vse skupaj v snake skin in to je to. ampak dobri pa so.
tako je dejansko z vsakimi kabli. vse skup nic a take cene, upraviceno ali ne.

na konec koncev razlike med kabli so slisne zaradi...
