Hi guys i planning to get a coaxial cable for me to connect my pc to my receiver.

i did some survey around in the forum, i found out some forumers DIY themselves.

So will there be big different in those coaxial cable?

some selling rm40-80 , some rm150+

i not a pro in music, so i really cant differentiate those sound quality .

any guidance from sifu ?

i planing either get monster cable or those cheap cable selling in AV shop

try the DIY AudioQuest HD-6A, only at RM 19/m

I think the 5 bucks cables sold in the department stores (Tesco, Carrefour etc) should suffice and serve the purpose..

Then try and borrow some 'esotic'/hifi cables and see(hear) if you can detect any differences and if you like it or not...

No point investing in Monster cables if your system is not up to it..

Diy yourself

If you are interested in DIY, I've got the instruction to do it, first time it took me 2 hours...now less than 10mins
Just read through it...it will take you less than 5min but saves you a lot of time and money in return.

Intro
There are two components to it...the Connector and the Cable.

1.I start with the easy one..the connector...you can buy this easily, usually can get good RM8 ones. What is important is the hole that the cable goes in, make sure it is not too loose or tight..the length is also important as depending on you equipment placement, too long also will be a problem if near to the wall.

If its loose, you need to use black electrical tape to fill in the gap, if too tight you need to scrape of the insulation a bit using a knife...take care..

2.Cables....there are MANY types...single, double, tri, quad shielding, 50 ohms, 75 ohms, solid core, stranded core, cheap, expensive, thick thin, you name it.
But what is most important is you get the best signals to the Receiver.
You can use RM5 dollar RCA cables also, I tried that, but somehow the sound wasn't right...and it was full of interference as my cable placement was limited...thats the main difference between them...due to the resistance, they can handle larger bandwidth and the shielding helps to reduce interference.

Its actually adequate to get RG6U cable 75ohm cable...preferably solid core. More expensive ones come with copper shielding instead of Aluminum...but it doesn't matter much if you are using it indoors.
No need to check the ohm with a multimeter as you will never get it.
When you go electrical shop...check the side markings on the cable..it is easily identify with is RG6/U. Actually, RG6U is the most common coaxial cable...but due to Malaysian ppl. like to cut cost, RG59U is more popular.
You can buy single, double etc shielding also depending on how you will route you cable from the PC to the Receiver.
Price depends...RM2~RM20 a feet for the common ones. Price depends on shielding, material used and brand.

3.How to assemble it.
Before I start, I say that I trust in proper connections with the Soldering Iron....so you need to get a soldering iron to unify the Solid core of the cable with the center of the Connector.
1.Make sure the length of the cable is enough, for first timers.....buy more..
2.Cut the other black insulation abt 20mm for the tip...do it slowly. What you will see is braided shielding and aluminum wrap..this is called the shielding. Simple unbraid it and pull it back together with the wrap. This will reveal the centor core insulator.

Cut the insulation abt 10mm to reveal the solid core.
3.Fit the cable to the connector, do some cutting to properly fit it.
4.Solder the center core to the center on the connector.
5.Crimp the Connector body to the braid and shielding.
6.Check and make sure NO braid or foil touches the Solid core. If you got multimeter, it is easy to know.
7. Wala..its done..

If you are interested, I can show you another picture of the inner 'works' of the connector. This one picture will help you a lot if you wanna DIY

Cheers

Thats very helpful, thanks for sharing.

Please read the tips I gave above if wanna DIY...5 minutes are reading and you can gain some knowledge...
It took me a long time to get those info and many DIY.

Here are some pictures for those interested..

Sorry...they are not new stuff or look a million bucks...


This is using normal RCA connector and a tri shielding coaxial cable...thats why so thick.
For those that can isolate the cable from other cable interference, single shielding is more than sufficient
Now, for more info....actually, all the Shielding are connected (or crimped) to the RCA body.
Even if it has 1,2,3 or 4 shielding, it all connects to the body of the RCA.
Those who don't know this, the body of the RCA actually connects to the grounding of the AVReceiver

This is single shielding type using RCA connectors and RG6/U cable. Its so simple to do..
I started with RM5 RCA cable (no shielding)...it sucked, then I went to DIY a 3 shielding coaxial....it was great, but later, I had to use a longer cable, so I DIY a single shield type, results are same as 3 shield...so sometimes...no need to overdo it
[attachmentid=1278808]


This is from another angle, check out the middle core is soldered to the middle of the connector.
Before you do this, make sure you use a sharp object to scratch the contact area to improve the solderbility.

Finish Product.....as you can see, the cable is thick and fit ngam - ngam with the connector...but in actual, I had to remove a bit of the insulation area to make it fit.
So make sure the connectors you buy is ngam with your cable. No point buying a thick cable but connector small hole

Happy DIY!!

Any question....ask..I'm not a sifu in electronics but willing to help.

Impressive!

Thanks...

I really not sure why but Coaxial Digital technology is more easily susceptible to interference from RFI and EMI ....thats why Shielding is used for their cables.

This coaxial technology is also used for satellite dishes and CCTV which needs the shielding as interference is a very big deal....I really dunno the theory behind it
i also like you...if can use RCA cables...why spend on coaxials?....but for me it was a different situation, I was getting a lot of interference by using RCA cables cause I hide all the wires together below the table top of the cabinet.

any sort of signal that is affected by transmission RLC is susceptible to noise regardless.
