They can't eat hdmi cable tho can they elf?

No but they could eat you. In fact, I might just come up there, chop you into little bits then prepare tasty, nutritious and exciting ready meals with your choicest cuts.

something more expensive would help with this or whether the sound just can't be processed quick enough by the receiver?

Probably not a cable problem - if you had a cable long enough to cause an audible delay, you'd have several miles of cable.

I'd try plugging an analog audio lead to your amp from wherever you have an audio out (tv, sky plus box ) to try and work out where the delay is coming from (sky plus, tv, amp )

its digital its fine

if you transfer an xl spreadsheet using a USB stick you dont loose any columns if you use a cheap one

i lol'd when the guy in richer sounds tried to tell me that i should spend 10% of the price id just paid for the tv on an hdmi cable

While what's running over the cable is notionally digital, it's effectively an analogue signal that's being transmitted. That signal's being sampled at the receiving end to work out whether a 1 or 0 was being sent, and the longer the cable or the poorer it's design/construction, the more degradation of the signal, and the higher the probability of errors. As a generalisation, error correction works, but only to a degree (tho' it's not the only way to get around errors).
Think of how freeview reception quickly goes from ok to a little bit crappy to completely unviewable, whereas analogue reception was always vaguely viewable even with all manner of reflections/interference, on the whole.

As previously said - short cable, anything cheap and nasty ought to work. A long run - you may need to spend some (sensible) money but I wouldn't have thought any more than a short way into double figures.

>I'd try plugging an analog audio lead to your amp from wherever you have an audio out (tv, sky plus box ) to try and work out where the delay is coming from (sky plus, tv, amp )

Yup, what Joe said.

a cheap one from a reputable source. You can get ones that work well for <£5 and certainly <£10. £18! They're taking the mickey. And as for ones more expensive than that 😆 Check out Amazon for some fair priced bargains at just a few quid. Longer runs (several metres), it's worth buying a more robust cable as you don't want it to break mid-run if someone runs the vacuum cleaner or a chair over it. All this 'OFC, directional blah blah blah' is marketing nonsense.

It's worth paying a [i]few [/i]quid for build quality, rather than buying crap that's going to fall apart after five minutes. Other than that, as others have said, quality (in terms of signal quality) is largely irrelevant, in contrast to the analogue interconnects of old.

HDMI has tight specifications that define how the cable (and everything else) performs. If a cable meets these specs, it's good whether it's a fiver or a hundred quid.

One thing of note, the HDMI spec gets revised. The revision of cable / component will till you what it supports (note - this is not the same as what features it has actually implemented). For instance, 3D TV [i]requires [/i]HDMI 1.4.

I think the PS3 uses HDMI 1.3 (google thisto be sure - I'm in the Xbox camp so I'm not 100% sure off the top of my head). Whatever it is, get a cable that matches or surpasses it.

So in summary, you want the cheapest HDMI 1.3 cable you can find that isn't made out of tinfoil and spongecake.

This looks the business.

Comes with a free TOSlink cable too, should you have an older amp kicking about. Bargain.

Maplin wanted £35 for one, so I bought one off ebay for a quid and a half posted which is just as good...

Just done a bit of reading.

The PS3 doesn't use the HD audio streams (which would require HDMI 1.3), but does support something called Deep Colour (which does need 1.3).

Also, there's category 1 and 2 cables; category 1 supports 720p / 1080i, whereas category 2 supports full 1080p.

In other words, the link I posted above is perfect, get it bought. (-:

I am wondering whether a "better" cable would work better in our home cinema system though - not for picture but for sound sync issues. The sound from our tv goes through Panasonics ARC (audio return channel) which sends it from the telly via hdmi lead to the bluray/sound system and then out through the 5.1 speakers rather than crappy tv ones. We sometimes experience the audio being out of sync (comes out slightly after the picture so the audio delay thing is useless, we need a picture delay!) using Sky+HD and just wondering whether something more expensive would help with this or whether the sound just can't be processed quick enough by the receiver? ton, any thoughts?

Send the audio direct from source to av amp via optical if your souce/amp has it.

And you can set an audio delay on a sky box - have you tried that?

And if a digital signal is just a digital signal why do all CD transports sounds different when plugged into the same DAC?

That'd be the "C" bit of the process.

Anyway what I've noticed after getting into various discussions about the best bike cleaner, the best cables etc etc, it that there's two groups of people.

The first is interested in learning and finding out what the best possible performance and quality they can obtain is. And is willing to pay for it.

The other is interested in getting something that works and is good enough.

No problem with either approach. Except the latter probably wear cheap suits. 😉

The only problem I have with that statement is the assumption that the two groups are mutually exclusive.

In this case, you can satisfy both criteria for under ten quid.

I'd say they are, something that "works and is good enough" is not the "best possible performance and quality"?

Unless you mean some people from both groups may wear cheap suits. 😮

Reminds me I must start a thread on bespoke suits.

I suspect there's a 3rd group, those that swallow advertising bumph & fuzzy scientific claims - hook, line & sinker

True. At least they'll be wearing good suits though. 😉

There's three groups. The first likes to absorb all the sales guff, has too much money and equates "best performance" to "best marketing". The second is the "works and is good enough" group. The third group is happy to spend the extra if there's evidence that it really is better.

I'd say there's always evidence something is better. Its just the extent of [i]how[/i] much better - and what that means to you.

Beaten to it!

Regarding the difference in CD transports, I had no idea what one was so Googled it, and came up with an article on timing jitter

Some people just don't appreciate quality.

I don't know much about video but in audio systems it's worth spending money on cable if you have high end equipment. True the price may seem incredible but when I listen to 'Down in the tube station at midnight' on my hifi I can actually hear Paul Weller's take-away curry hitting the platform. It's very moving & something completely missed using cheap cables.

just a quick heads up for you guys that think a costlier hdmi lead is a better one.
i buy them in 100's.
ones i sell at £1.99 cost me £0.79p
ones i sell at £49.99 cost me £2.50........... 😳

Where do you work? Do tell.

That to me isn't an issue with cable quality, its an issue with unscrupulous retailers.

danmo........my prices are trade.........just think of the mark up people like richers/maplins/currys/comet are making.

get real boys...........a cheap £1.99 one is just as good. it just aint packaged as nice........ 😆

Retailers make pretty much the same mark up across products in one segment. For example in fashion, pretty much everything is marked up by 2.7 to 3 times.

If you are buying something at £2.50 and selling at £49.99 then either you are selling way about the manufacturers RRP or selling something cheap for a very expensive price.

There is no manufacturer who would allow a retailer those kind of mark ups. They would take it for themselves if costs were so low and such a high market price (relative to cost) achievable.

I stand to be corrected though, who is the manufacturer? Or are you just passing off cheap products?

If you're running Blu Ray to a HD Projector then yes. I noticed a massive difference changed to Chord cables.

hilarious.

And if a digital signal is just a digital signal why do all CD transports sounds different when plugged into the same DAC?

because it's a human listening to them.

Why dont you get your Blu Ray player and your HD projector set up and try swapping between a cheap 10m cable and a decent 10m cable?

Send the audio direct from source to av amp via optical if your souce/amp has it.

And you can set an audio delay on a sky box - have you tried that?

Audio delay makes it worse, as the picture comes out before the audio - as I said if anything we need picture delay. Apparently the device has an "auto lip sync" feature I'm gonna try, but it looks like it only delays the audio. Apparently the Panasonic ARC/Viera Link may need a 1.4 cable, the one I have is a 1.3a if that makes any difference? Gonna ring em up to see what type it actually needs as the manual is bloody useless!

It seems to work fine and in sync using the RCA Aux output from the tv into the Aux input of the amp which makes me think the ARC feature just isn't good enough. Ok so I could just make do and use the aux but the amp doesn't default to aux and takes ages to switch between input sources, and ARC allows you to control everything through 1 remote which is nice. Plus it turns the amp on and off when the tv is switched.

Considering we paid about £500 for the cinema system we shouldn't have to compromise and use the aux and not benefit from the ARC/Viera Link features.. which is what I'll tell Panasonic tomorrow.

The wikipedia page for HDMI standards says that 1.3 versions don't support Audio Return Channel, yet 1.4 versions do, so this could be the problem.

Are there [b][i]any[/i][/b] facts/science in that article from [u]1993[/u]?

I did like this bit...

why don't poor (high-jitter) transports all have the same sonic signature? What mechanisms create such a broad palate of sonic flavors? There are two possible answers. The first is that, besides the bits and the timing of those bits, sound quality is influenced by a third, unknown factor.

Not sure then, maybe worth speaking to SKY as perhaps the box is slow processing audio. Is it only on HD channels? Maybe you have this issue? [url= http://community.whathifi.com/forums/t/123963.aspx ]http://community.whathifi.com/forums/t/123963.aspx[/url]
