Topic: CCA vs OFC Power Cable

[finalazy84]

as for the power cable, as long as it is capable to deliver enough amount of current to ur amp then I think it is fine.y must copper?if u relize, OFC and CCA cables, CCA is much bigger than OFC.that means CCA need to b tat big to have a same resistance value to OFC.we want a cable that not too big that occupies our space but still reliable and not easily oxidize.our car chassis on the other hand is not made of copper but it is big enough to transfer the current.the only thing u need to remember is the cable at ur batt (-)ve terminal.is it big enough?

u r rite about the speaker cables n RCAs. cos some signal might lost if u r using a cheap one.
dont worry to much, u shud watch this vid.it is not about cables  http://www.youtube.com/watch?v=BYTlN6wjcvQ

we have a customized DC harness for Mcintosh HU for sale.
DC harness is used to connect from DC-DC converter to MX406/MX4000/MX5000
the unique of this cables were oxygen free copper with high purity + lead free solder

by replacing this DC harness(customized by audio creations), i assured you can hear the diff. again u dont need to have golden ear to hear the difference. its a plug-and-play game. simply cant lie!!

so, the test above shows the importance of using high purity copper. u can literally hear the diff.
some of the ICER here, has this customized DC harness.

the respond from most of them
" wow.. like dat oso got difference"
" only cost couple of hundreds, can improved SQ so much"
" never knew a DC harness can make a difference in SQ"

conclusion: high purity copper

sorry..this is off topic a bit
but i have to share this

latest customer comment:
" eh..why u sent me a charm!!..this small little PCB board can make so much diff wor"

funniest comment we received from customer after modding upgraded clock on the HU

But the problem is, everyone that from "high end" acc shop or hi-fi shop don't like Ethan Winer. Because this fellow bust a lot of myths on this field. If you watch and understand this video 50%(I watched it 20 times already and even created a DVD for it) then you will know that a lot of current practise and concept applied are not ethical and are useless.
Also if you visited recent KL AV show, there's a fellow selling rm800 sonic enhancer that consist of some plastic and a very very thin wire with crocodile clip. If you understand this video, then you will know that this sonic enhancer are useless actually. But still got people clever enough to buy such product and start boast around that it helps.
Lay another 4AWG from your amp to battery direct make wonders.

woh, taikor edy in, I cabut first b4 got flamed kaw kaw

Well, why you want to run? This video is really informative... If you really scare, you should not post this video, because this video is very damaging to this industry(especially for those want to sell cheapo stuffs at expensive price).

A lot of people like to say using expensive stuffs can give you the best sound, but that's not true. This is where "expectation bias" and "preception bias" from this video comes about. A good tuner/installer won't bother much on the equipments used, but will focus more on the speaker placements, which is more important.
Think it this way, if those so-called high purity copper are really that good, why not people use it on industry?

[finalazy84]

hehe want to cabut oso got flamed 

btw,that is so true.sometimes the brand oso make us feel it sounds great until we meet someone wif mid end system (without knowing it) and it sound more or less the same.tats y I post this vid to iamkroll so he is not too worried about those cables untill he forgot bout other important stuff to make his system better.

BTW, I hit the reply button too fast, if you browse Belden speaker wires(don't care on the size) on their website, you will see that their spec includes inductive, capacitance. If you choose the "right" wire for the "right" applications, you will be amazed on this.
Our car power are really "dirty" because of the RFI generated from the alternator. So picking the "correct" ferrite core or the coil that come with middle end HUs(like P80, 9887....) will be good enough already. If you are able to see the Pioneer's ODR power filter's internal, you will see it is made from an inductor coil with ferrite core and a 33000uf capacitor. And this fellow cost you rm1500.

simple kyo111, if people are worried about getting conned or worried if the item does not work with their set-up, they can always ask for some sort of money back guarantee. if the manufacturer or applicator have something substantial, he/she will be more than willing to take the items back with full refund. the more manipulative ones will ask you to exchange for something else, or some may even offer to loan you the item on trial because it does not worth much anyway.

basically, we must learn to differentiate a "consumer" targetted item (product) built for the mass market to a purposed "people that know their stuff" targetted item that has gone through real research and professional evaluation at very high expectations.

if we just write off everything due to the money making bad eggs (whether they are reasonable or high priced), then we are pretty much stuck at the same level of crappy hifi for life. nobody will bother to invent anything new and we will still be riding bicycles to work.

the more i think about it, the more ideas i get. lets say cables do nothing but colour the signal.

this means that whatever the cable manufacturer claim the wire will do (e.g more natural sound), is may not be correct. because if u want the most natural sound coming out of ur system, you have to use the same wire thats inside your system components. eg. if amp A has X wire soldered inside it, the RCA has to be of the same wire. if we use a different wire, then this wire will 'colour' the signal and it wont be the natural sound of the amp.

lets say amp A produces red sound, and cable X claims that their cable will give a yellow sound. the bi-product in the end will be orange. what if another amp B produces a blue colour.. using the same cable, the outcome will be green! lol.

amp A = red
amp B = blue
cable X = yellow

therefore:
amp A + cable X = orange
amp B + cable X = green

so whatever the cable manufacturer claim it to sound, may not exactly give the intended sound!

LOL i think this is too much wei!

alamak... hehe

iamkroll, this is how i see things. hope it makes sense to you.

to put things simply, color or no color depends on what you want to achieve at the end. if you achieve what you want to achieve, then what ever cost clearly becomes justifiable. if you do not achieve it, even little money may never be justifiable.

if the end (goal) is Z, it can be whatever combo of amp, cables etc. that will give you closest to Z possible. if cost is an issue, your choice of variable to achieve Z is limited and you may not get very close to it.

if you are exposed to limited colors, then it is easier to achieve but if your color palette is exotic, due to exposure and a higher benchmark, you may require certain variables to achieve your heightened demand.

haha...thats too much bro...
myb we shud listen to ICE sifu...they can clear this to u...hehe dont listen to me Im only a noob  

from my point of view, the end result depends on u aclty.u buy what u like.not other people like.it doesnt matter it is purple or pink.after all, u r the one that will listen to it.so that means u need to know all the right combination which suit u.

edit: nah see...told ya hehe

lol my thoughts exactly! was gonna put that as my next post. if desired end colour is white, basically your system colour must consist of all the rainbow colour spectrum!

[iamkroll]

but then again, there are SHADES of colours. so that makes it tougher :P

[rbl84]

i m noob la duuno wht u ppl r discussing...sounds like mixing kansai paint to me :S sob sob.....
