Only difference is the quality of the cable itself i.e. the connectors, built quality but in term of signal, very minimal ..
*
So how do you judge the build quality of the cable itself?

Thicker is better? Got braid or not? Metal vs plastic connector plug? Got ferrite bead or not? ...do these things make any practical difference?

People already said the signal for digital is 0 or 1.  So, not matter what make the HDMI cable, you still received 0 or 1 signal.  You think better quality HDMI can produced 0 or 1 in this form: 0 or 1laugh.gif

So, do you think if machine received better looking 1 or 0  tongue.gif , your picture and audio qualities will be better?  rclxub.gif

Conclusion, if your HDMI cable can received 0 or 1 signal (mean it is good HDMI cable) or can't received 0 or 1 signal (mean this is defect HDMI cable). That's all, case closed.  whistling.gif

I suppose in a very general sense what you say is correct. A lot of people say digital is digital, it is either received or not received. But if you look at the details there are still some slight differences but which I don't fully understand. Have a look at this article: http://www.audioholics.com/education/cable...ble-bench-tests - in particular read about the test equipment and the eye pattern.

Another theory of mine, yes bits are either 0 or 1. But a signal isn't just 1 bit, it's not a case of cannot receive a 0 or 1 signal = complete failure. In one second megabits of signal is passed through the cable, what if the cable is not capable of transmitting all the bits perfectly? What if only 99.9998% are ok and the 0.0002% is not received? How does this affect the audio/video?

thinking about the tramission of all the bits.
If we are copying a excel file from a ext HDD to a PC via a cheapo USB cable. If the USB cable only can transmit 99.9998%, theoretically the excel file is incomplete and some data is missing. But this does not happen even though most people uses regular USB cable.

Thus I still don't understand the expensive HDMIs...
*
From the cross section view, HDMI cable looks more complex than USB cable. Perhaps HDMI signal also more complex?

Anyway, those expensive branded HDMI cables are relying on audiophile branding to charge more smile.gif What is there to understand - just that someone, somewhere is laughing all the way to the bank! tongue.gif

I'm using one of these, but shorter length
even with vPost shipping I think it will be cheaper than any brand name cable you can buy locally. Perhaps you can gather some other people who maybe interested and make a bulk order
*
Very good price that one.

Alternatively can try this forummer: http://forum.lowyat.net/index.php?showtopic=815300 They have 10m for RM126.

y is it when you use a cardas interconnect, you get better bass,
an audio quest, you get better treble
maybe van del hul, a more soothing sound

what about the transparency, soundstage, depth, etc??
*
What type of interconnect are you referring to above? HDMI cable, optical cable or the analogue RCA cable?

bro anfield, dont know whether its noise or not

one displayed blurrer pictures, and certain brightly lit spots appeared smeared (bigger...of cos not measurable la biggrin.gif )

have to use the pioneer BD to calibrate the Detail level up ( there's improvement ) but cant better the other cable smile.gif

i also did freeze frame on facial, and did swapping few times, the wreckles, facial pores ( dont know wat you call it.. mind my inglish..hehe) seems clearer.

one very good example is on the spiderman 3, when the SandMan finally gather back its figure, notice the "details" grains of sand flowing/streaming along, and when he picks up the pendant on 1st attempt, notice the expression (details on eye)
you really dont have to pause/freeze to just let it play and replay

happy experimenting !!! biggrin.gif

What were the two HDMI cables used in this comparison?

Interesting.

The HDMI cable was used between the LX-52 and your Yammy right?

Taiwan got produce HDMI cable? Which brand, Usher?

Monster Cable is brand of cables. It's more expensive than your normal cable, but not necessarily better.

What kind of noise do you hear when watching movies? It may or may not be a cable problem.

HDMI cables can be tested to different specs. Just like network cables have Cat 5 or Cat 6. The question is how do these technical specs correlate to practical use?

good cables do make a difference, perhaps not in the picture quality/processing but more towards data transmittion. A better built cable will be able to transmit the data more reliably. Signal loss happens more frequently on poorly built cables.
*
On this point, I just read on wired.com:

The claim that "digital cables, by definition, have no signal loss" is indeed false. It’s only true if the transmission is error-corrected, for example by using a protocol like IP. Without error correction, the stream of ones and zeroes can lose integrity en-route just like an analog wave. DVI and HDMI are not error corrected.

So that implies that transmission error / signal loss could potentially occur in poorly built HDMI cables.

Thanks for the notes on jitter and parity data.

Like you said, if there is a problem with the signal the visual problem will not be subtle. The visual degradation will be apparent. On the other hand, claims that the visual will be improved (brighter colours, sharper images, etc) are subject to much doubt.

I think you should be able to tell the counterfeit cable by looking at it. It cannot be exactly the same.

I haven't seen the fake one before, so I can't tell you the difference.

To be safe, avoid buying M1000HD HDMI cables at very low prices.

Buy from a reputable sellers (like me wink.gif) to ensure you are getting the real thing.

All the Monster cables I'm selling are 100% genuine.
*
As you know, fake products are getting better and better, and it's not easy to tell the fake apart from the genuine. Also not many people will have a genuine Monster Cable to compare to.

Anyway, can I ask how you can be sure your cables are 100% genuine? If you are buying from a supplier in the Far East, can you be sure they are selling to you the original?

Just to clarify my standing and credibility as a Monster cable online seller, I am getting the stocks from an authorised Monster reseller in the US. They are getting the stock directly from Monster Cable in California.

Thanks for clarifying your position in this matter and where you get your stock from.
