I guess this is not the proper way to compare HDMI cables because most of you feel that they're the same whether it is a Cap Ayam brand or a branded one. Certain brands like Monster Cable for example has HDMI cables with a length of 12 metres and above and it can still output 1080p signals with no problems but try using a Cap Ayam brand, you'll notice that there's nothing on the screen. There are many cheap Made In China HDMI cables costing only RM50 for a 7 metre length but what most people didn't realise is that such cables can't carry HD resolutions at this length, it works fine with 480p but not with 720p. When you manage to get one, then you'll know where branded HDMI cables will shine.

Next, if you know, uncompressed audio is transmitted via HDMI and we're talking about a very large bandwidth involved here so that the signal strength must be strong and stable, the resistance in the cable must be kept to a minimum. No two HDMI cables carry the same bandwidth as they're made with different materials and if you're using them merely for an upscaling dvd player or video game consoles, you won't notice any difference until you're passing uncompressed audio to those next-gen amps which are already out in the market now.

Most people think that as long as it's digital, it doesn't matter that much but for the trained ears, you can detect the difference. It's true even for coaxial and optical cables too, better ones do make a difference but if you're having a budget setup, then it's not feasible to get expensive cables as a poor source won't do any good even if you have high quality cables. Lets not argue about this, just suit your pocket, if you feel that it's not worth dumping extra $$$ on cables, then lets just move on.

But we weren't talking about extreme length of cables. smile.gif

You have just reinforced what I have been saying. If the HDMI cable is too long you just don't get a signal that's all. There's no in between like a blur pic or a dull pic.

Most cap ayam brand even up to 5 meters can carry a signal without problem. So whether Cap Ayam or Expensive Cables there's no diffference.

As for Optical and Coaxial, I don't want to comment there because both are using different technologies. The peculiarities of the implementation of the signals and the conversion of the signals to analog might give rise to some differences. smile.gif

Good idea. There's no point arguing with audiophile lunatics, especailly those who think that a RM900 1 meter power cord can perceivably influence a player's sound (notwithstanding that electricity is supplied with gimmick-free cabling from the nearest neighborhood TNB station kilometers away!).

Anyway, my take in this is that if a cheap cable works out for you, keep using it. The risk with buying a cheap cable is that you may have to buy a second cable if it turns out that it doesn't work (and thus spend more) or when your requirements increase. It has happened to me before when the 5m cable for hooking my DVI-D monitor to the computer in the closet didn't work past 800x600.

Power chords has nothing to do with what we were discussing. We were discussing digital HDMI signals on different quality cables. smile.gif

If I buy a cheap RM30/- HDMI cable and it loses signal after 1 year, I just buy another one.

I still save tons of money rather than buying an expensive one which does the same thing smile.gif

Cheap HDMI cables = If it works, it works. No difference with Super Duper Cable.

Cheap HDMI cables = If it doesn't work, just loss of signal that's all (Image won't dim or blur). Buy a better one. Still cheaper than buy an expensive one.

smile.gif Peace, Just friendly discussion.

Try the computer shops like All IT Hypermart. They might have. But not too sure they are cap Ayam or not.

It's easier to find Cap Ayam HDMI Cable nowadays, but for DVI-HDMI converter cable not as common, so don't know much about Cap Ayam.

How about explanation like this ??

Expensive Cable: Got image
Cheap Cable: No image or got image

After few years

Expensive Cable: Still got image
Cheap Cable: Might be no image output

Haha not that bad lah. biggrin.gif . Only if really extremely bad quality, or very long length, then no image.

If you are buying just 2 meter length cap ayam cable it shouldn't have any problem at all. Maybe can even last longer than your TV. Just don't damage the cable especially the connection ends that's all. If you buy longer than 3m then better get better quality ones.

Don't worry, even if no image after few years can buy another cheap one. By that time even very expensive ones already become cheap. So save a lot of money in long run. Price difference now between cheap cable and very expensive cable can be >5 times the price.

Most important is both Cheap and Expensive cable also give the same image quality.

The cost of the HDMI cable must be justifiable to your system setup. no point buying hi-end HDMI which cost near to a thousand when you are just using HTiB system costing RM2-3K or so connected to a 32".

In this case, a normal or mid-range HDMI will do the job.

I just believe a high grade cable will give the best picture quality when partnered with the right equipment. I have done A-B comparisons before so there's a difference in picture quality, it's not about whether the picture appears or not, you have to look closely, the finer details in the background, the noise, colour saturation, blah, blah, blah. Of course, if your HT setup is in the budget range, most likely these cables won't do much difference to your HT setup and you might be cursing non-stop that these cables don't work at all. A high grade cable will be made with the best materials and some with silver plating, 24K gold plated connectors.

Even for power cords, they're neither analogue or digital but a better power cord will make a difference. To convince yourself that they do make a difference, try going to CMY Sungei Way (the other outlet on the top floor), find this guy, Richard. You can make an A to B comparison with their QED, Siltech or Richard Gray power cords, QED HDMI cables, bring your own software and test it on their HT setup, you'll be amazed wit what you're hearing and seeing. Of course, you can go to A&L Sungei Wang as well to try out their Audioquest stuff. Well, even my old Supra power cords connected to my pc gaming rig, made a difference in the picture and sound quality. It's not necessary that such cables are expensive as there are some which are value for money and rated editor's choice too.

Since talking about cables can also turn into a heated argument. sweat.gif Well, I rest my case here. It's your money, it's your call but I believe what's best for myself. For me I wouldn't want to mess up my HT setup which I've spent a fortune on, I wouldn't want a few 'Cap Ayam' cables to hold it back.

Not really heated argument, don't take it the wrong way smile.gif . Just that some of us are expressing different opinions that's all.

When testing it need to be done on same display using same player and same input. That's because different inputs can have different memory settings. One can even adjust one HDMI input to make cap ayam look better than an Expensive cable on another HDMI input on the same panel. You never know the tricks used.

The best is to ask someone to randomly connect the player to the same HDMI input using the Cap Ayam and the Expensive cable while your back is turned. Do it 5 to 10 times randomly without the person telling you which cable he is using. HE then notes down the sequence and you also notes down what your guess is.

Then compare whether you have got it 100% correct. If you have mixed results then all I can say is it's all in your mind smile.gif

I also realised I have dwelled to much on this topic. So I guess I have said all I have to say. Just realised that some people here might be selling these expensive cables, so don't want to affect their ricebowl with my comments smile.gif

I will say get cables from reputable brands than getting those unknown brands costing thousands and not a single review in the magazines. There are those so called branded cables, imported from Sweden lah, Germany lah, blah, blah, blah .... they dun even have a website but some shops will tell you, they're better than Monster Cable, VDH, IXOS, Wireworld, Cardas, etc. Most Hi-Fi shops think we're waterfish by pushing unknown brands to us, have went to a few Hi-Fi shops in KL, some of them tried to push these rubbish to me. They didn't know I won't fall for their tricks. wink.gif

Cap Ayam cables also got good quality ones but you need to test it on the spot to see if it lives up to your expectation, not all Cap Ayam cables are bad but I'm saying the majority ones in the market are bad so it leaves a very bad impression when we mention about Cap Ayam ones. I noticed, we'll have less problems with Cap Ayam audio cables, digital cables and analogue video cables (i.e. s-video, component video) than HDMI or DVI cables. My friend bought a HDMI cable at a very cheap price from Japan Pasar, RM25 for 3 metres and you'll be surprised to know, it can't do 1080i / 1080p, the screen will go blank but it's okay if played at 720p resolution and below. The shop refused to replace or refund back his money saying that they don't guarantee such cables to work at high resolution. vmad.gif Very dishonest I must say.

Ngto is right, whatever cables we wanna buy, definitely must test kaw kaw before buying, no point buying something that doesn't improve even a little bit in the picture or sound quality department. I usually bring my own softwares to test and I'll inspect everything as well, I'll make sure that they're actually using the cable I want to test, some Hi-Fi shops have a bypass switch hidden somewhere. Unsuspecting buyers will kena for sure especially when they're testing a pair of small speakers, they have a subwoofer hidden nearby which is actually connected to the amp so people might think that wow, such small speakers can produce such good bass, imagine go home and test, the sound even worst than a pair of Altec Lansing. doh.gif

If not, some Hi-Fi shops use all those high end cables in their audio room so even if you buy a budget range Hi-Fi setup, chances are you won't be listening to the same sound quality when you listen them at home. Don't forget such places even have a power conditioner that cost thousands. With all these goodies, anything dull sounding, will sound slightly better.

It's possible, it's the same guy that I'm talking about as the previous time I went to Sungei Way, I didn't see him there, only a girl and another man. I thought he was on leave that day. laugh.gif

You can ask him to test anything you want, he's a very nice guy and he told me that it's okay if I dun buy anything from him, most importantly I'm satisfied with the sound, if not, what's the point of buying. Very sporting, eh? wink.gif

wah this richard has been based in pyramid for like around 2 years la.....hmm.when was the last time u went to sungei way first? tongue.gif

abt testing the cables...i'm more into movies than music and since hdmi is the best we can get for video...a lot of shops i went to are trying to push their HDMI cable to me. but they said cannot open up and test the cable. and i'm not gonna be taken for a ride and believe everything they say abt their cables, so it's a catch 22 situation

I agree with Sunauto that a RM25/- HDMI cable is really pushing it too far. I am not surprised that it has no signal for anything above 720P.

On the topic of HDMI ver 1.3 1080P, I myself wouldn't go for anything below RM100/- for a 2meter length cable. The Specs for V1.3 itself require better quality cables to carry the signal through.

I figure very soon we will see cables labeled as HDMI 1.3 compliant if not already so.

Got signal... got picture... no signal. no picture.
So, our so called theory is still correct.

Cheap or expensive... it will not affect the quality of the picture. That's all.
But yeah... cheap quality cable might just fail you. MIGHT!

In short the LCD TV doesn't care what quality the HDMI cable is as long as it is good enough to carry all the data intact without errors.

Just like installing Windows XP using a low quality pirated disc and an original high quality disc. As long as the low quality pirated disc is error free you still get the same Windows XP. If the disc is really bad you just get a corrupted computer that hang that's all.

If the Windows XP is an audio cd or if the multimedia contents are streamed off the disc, there will be a difference if it's pirated. I never buy pirated audio cds because of this but for movies, I got no choice lah, not all movies are released here locally.

Well, some people feels that spending money on cables are a waste of money but they can afford to buy a LCD / Plasma costing a few months of their salary. It's the same like some people that I know, can afford to buy a BMW but using cheapo Sime tyres. Their argument, the car can move enough lah. doh.gif

Digital is digital...1 and 0 of info... HDMI is essentially SL-DVI ... there is no distinction whether the 1 and 0 travels through gold/sliver/platinum or even plain copper/tin/graphite... No HDMI cable should cost more than an ordinary SL-DVI cable.

A more accurate comparison would be... The same coke from the supermarket or served at a high class restaurant at 10x the price... same liquid in tummy but with a less money in the pocket.

Let me clarify if you don't mind smile.gif

I was merely using WinXP example to illustrate how digital data arrives intact over different quality medium.

You example of Pirated disc contents (Audio CD/Movies) , is not related to our subject of discussion. That deals with the quality of the source data itself. We were discussing about the medium over which the data is transferrred i.e the HDMI cable.

You example of Audio CD is also interesting. We have been saying all along that Analog is different from digital (Unless you were referring to digital Audio.)

Your use of Cheap Sime tyres as an example is also interesting.

Let me ask you a question if you don't mind smile.gif If the cheap Sime tyres can perform exactly like a RM10,000/- set of tyres (EXACTLY in every way, not just "the car can move enough lah") , would you still buy the RM10,000/- tyres?

Hehe, I have a feeling you would still say yes. smile.gif

I always seem to stir up people to respond. Next time I will really try not to click on this topic.

Sunauto knows I am really edgy regarding certain unresolved matters (not with him smile.gif ), so have to channel my frustrations somewhere.

Pirated audio cd comes from mp3. If you take an original music cd , rip it off from a good cd writer digitally to wave format and then manufacture it again,it will sound the same.
