想問有沒有朋友DIY電源線, 效果好好?

想問有沒有朋友DIY電源線, 效果好好?

有試過，靚不靚聲則視乎線材了。
還有一點很重要是，所做的電線是要有電牌才可以的。

有冇好介紹?

You may try FP-3TS20 by 古河

I am using it as Power cord for my CDP

Hi audionote,

I had DIY 1 power cord using cheap material (ampcom CAT 5), IEC from farnell and normal socket), i dare not say good but it is satisfy. Better than supra (RM250 ~HK500). More or less equal to audioquest (rm900~hk1800) power cord. Observation is done by my friend & me so it is quite subjective. For those not willing to spend high budget on power cord can try...

If u can get better material like belden cable (if possible >5N copper), good socket & IEC plug) it will be better.

But must be very very care while construct the cable... if u mix one of it --> minor case-->fuse jump/blow, seriouse case your amp burn....

2) u need to try & error on the distance of spriral for the ground... to find the sound suit u...

i had use this cable > 1 year in my system...satisfy with it...
Anyway some expert may not agree on this type of construction for power code...as it normally use for speaker cable...

Attached the photo for your refrence.

woww, amazing, only seen in speaker cable
now even in power cord
brilliant... ~!
but what would be it's nature of sound? warm? fast, analytical ? all round? etc etc?
thanks

window

you catch wrong guy



I saw you cable and feel you are DIY MADNESS. :shock:


Do not upset what I said. :

Audionote,

Yaloh...audiolab become audionote...my eye blur already...sorry oh...

Don't worry.....u r not 1st person said i'm mad...crazyman normally won't be upset by other people..... we live in our own world : )

i always remember a word"活在当下“...when u can do & try..don't wait....


Maybe i study too much science & like to bahave as mad sciencetist....
Edison try 400time only invented the light bulb.... then more scientist base on light bulb basic to invent other thing like tube & x-ray....

I initially just try VH audio chris's way of DIY power cord using 2 twisted pure cu (6N), later after i DIY the speaker cable using cat5 i found the result is very good.... then i'm thinking if the tweist is to reduce interfernce & noise, then a cat5 type of pwer code should be better than a pair of twister able... so i try and found the cheap cat5 (<4N) even sound better than teh 6N twisted.... even though Chris (VH audio) not very agree on this construction (safety issue).

I'm not sure whether this power cord bring good effect to those who had use regulator/stabilizer. But for me n my friend, we didn't use regulator/stabilizer, so this power cord really good to reduce the noise.

After we use it (ESPECIALLY ON AMPLIFIER), the noise reduce a lot-->background much clean, sound stage clearer, the air space increase, sound stand out a lot. It's effect is more than a cat5 speaker cable....

mbcy,
the ground cable & purity of the cu play a role on affecting sound quality.
so u need to play around to find the sound suit u...

our experience is that if distance  between helix fot ground cable too near (sound will become soft, bass soft a bit), when too far away sound will be a bit harsh since grounding not enough.

as we know there is "skin effect" high frequency travel more on sufface of the conductor, low frequency travel more deep.
if not mistaken 10kHz travel ~0.6mm of the cu conductor.
As such thicker a cable will get more bass, purer ther cu, bass can travel faster so bass-->fast & tight (so cu purity play role here).

i guess if u can get TFTF insulated CAT5/cat6, >4N cu, the effect will be much better!!



AGAIN REMINDER!!! MAKE SURE U DON'T MIX EVEN 1 CABLE (U got 27pair, u mix up 1, u may have problem) i will advise you to try on other electronic part like kettle.  I had mix 1 of the cable initially, lucky just jump fuse...."god very kind to me"....

This is the most "scientific" way to intepret / analyze a cable

fabulous~~~! :twisted:

用CAT 5線做電源線太危險了,它的膠皮太薄,大電流會產生熱力使它硬化,長時間使用可能會溶或龜裂而short,最起碼L,N,E各自套通再織成,

kin,

U are right!!! so if anybody 12 try this must use CAT5 with good quality jacket and dun twist too hard, let more space in between....or use silicon glue for who cable....

1 of info on skin effect is found in this website:
http://en.wikipedia.org/wiki/Skin_effect

e.g of depth travel by electric in copper:

frequency     d
60 Hz          8.57 mm
10 kHz        0.66 mm
100 kHz       0.21 mm
1 MHz          66 µm
10 MHz         21 µm

such info may help u in construct speaker cable/ hook up cable. Some people use this to reduce booming thus they will use only 1 pair single core twisted cat 5....

最好用耐高温的特富龙外皮线，就算薄一点都安全一些，一般电源线的导体面积有2平方毫米以上就足够了，如果是一般的PVC绝缘，流通电流在15A以下是安全的，要是特富龙外皮绝缘，流通电流可在20A左右，不过并没有那一台功放长时间都要求提供10A的电流，大电流多是瞬间很短时的供应。对于电源线来说，导体在12AWG左右就OK了！

CAT5線是不合適的線，絕對不能做電源線，大家還是小心。

Use CAT5 --> Too dangerous.

For the cable rule, remember the resonant freq. (Impedance of the cable), read the spec from the cable manufacturer, select the right cut off point (i.e. length)

--> Characterisitc impedance !!!

I think KK & MODI sir are right. So advise other not to use CAT5 like me a spower cord.... later i shall construct another cable using more safe material....

我曾買DENKO 日本無酸銅作入墻電線，再用剩下的線打孖作一條電源線，感覺很此線背景很寧靜，音樂感很好!
我想影響線材的導電率最重要的因素是材質、截面積，當材質相差無幾時，截面積影響更大。雙股線導電面積大一倍(每條2.5MM，雙股達5MM)。不知是否正確。

why,

i agree with u that cross-section diameter  & conductivity is important factor. But other than there is other factor. --> the method use to reduce noice/interference/electromagnetic flux.
anyway, for me if possible i prefer the total diameter of 1side(either life/neutral) is >5mm.

As we know that when electric flow into a cable electromagnetic wave is generated, the better the conductivity-->faster flow-->higher electromagnetic flucx (that why the electromagetic field is very high for superconductor-->e.g in manegtic resonance imaging (MRI).

Twisted method is use to reduce the interference.
The question now is:
1) for thin wire --> can do more twist--> can reduce more noise
2) thick cable with thick coating-->less twist--> less noise reduction..
so sometimes multiple twisted thin cable may give good result...
