Is there a difference in HDMI cables?

I run a 3' HDMI to the Reciever, 3' HDMI to the Balun, through 30' Cat5, and another 3' HDMI cable, and I can't honestly say I've noticed a difference in PQ from when I had a 20' run of HDMI straight from the BRP to the PJ, other than a slight flicker when the fridge downstairs turns on and off.

Does that mean anything?

:razz:

Yes it does , you should have a dedicated circuit for your equipment , your causing internal Brown outs in your own house. it will wear your gear out over time or could cause failure.

What I would like to know is how does Audioquest know how the song is supposed to sound, did they write it no.
Therefore how oes one determine how exactly is a song supposed to sound exactly as the artist intended.
Did the artist use Audioquest cables and mics and Vodka cables?
We listen to music day in and day out sometimes critically but do we actually know exactly how it's supposed to sound, I'm guessing only the artist can verify if these Vodka cables actually do his music justice or if he hears it changeling things that he did not intend.
I'm only asking because I don't know, how do we know the "drastic" improvment the cable causes is what the artist music is missing and not just adding something into the music because they Audioquest think they are correct?
I saw DSkip posting about Tool I believe the song 10,000 day wings part 2' he said he now hears the thunder coming over head, when I listen to it I hear the thunder coming from a distance in front of me then as the song progresses it gets closer and closer till it raining and overhead, very cool..
Who's correct only Tool can answer that right?
Everybody is different and has certain preferences when they listen to music after all it's all in your head..

You are missing the entire point of having good quality cables anywhere in your system. It's not about how it's supposed to sound and making the cables to make the sound sound exactly how it was recorded , it's about preserving the signal so it can play exactly how it was recorded. If you use cable A and it sounds one way and cable B sounds another , something in one of the cables is not doing it's job correctly. These Network cables could possibly be bull or they could retain the signal perfectly. I know for a fact not all ethernet cables are the same as they test differently. I'm well trained in Audioquest and I know for a fact they are super anal about everything they build. All of their cables are built to the highest standard. It's a reason why all of their entry level cables are fantastic.

Just looked at Oppo's site. No brand listed on their HDMI cables. The cable that is included with their players sells for 10.00 separately in their accessories section. Logic: Being that Oppo is a world renowned BD manufacturer does it make sense that they would include a HDMI cable that would be sub-par to the quality standards needed for their players?

Do you also believe that the generic power cord or patch cords that come with some gear are as good as it gets?

You didn't answer the question which required only a simple "yes" or "no" answer.....or, possibly "maybe" if you weren't sure, lol! For simplicities sake let's put it like this: If you were the CEO of Oppo would you purposefully make the decision to include an audio accessory that you knew would compromise the audio/video capability of your products? (yes or no?) If you were the CEO of Mercedes would you purposely make the decision to put tires on your automobiles that you knew would compromise the quality of the ride? (yes or no?) I do believe that Oppo knows more about cables, and that Mercedes knows more about tires than you or I? Do I believe that generic anything is as good as it gets? Funny! Is this a trick question? Lol! Do I believe that world renowned high profile manufacturers of anything know when it is not an improvement to include a more expensive component? Give the choices of answering "yes" or "no" I answer.....hmmmm? Let me think on that and get back to ya! Lol! Goodnight Everybody!

Do you believe every manufacturer decision of anything is done purely for intended purpose? You have to be kidding if you think there's nothing better then what came with said item.

Yes.
But that's a poorly worded question, IMO. A straw dog, of sorts, by the use of the perjorative word "compromise".

The CEO of Oppo has many considerations when designing a product for sale. It all boils down to what is the threshold level for "Good Enough" to maintain brand integrity, sustain sales, and still make an acceptable profit.

The CEO of Colby/SoundDesign/Magnavox has a different threshold, IMO.
"Did it catch on fire when you plugged it in ? No ? Good !".
And the market they target knows and/or doesn't care about the level of performance they get with that brand.
Pure price point. Is it cheap ? If "Yes", then the threshold level has been met.

Oppo, targets an audience with a little fatter wallet.
They know and expect a higher level of performance, to a certain degree based upon brand recognition.
Price point and performance are both considerations at this level.
The threshold level is higher.

Moving up the food chain, the threshold level rises dramatically in price and to a diminishing degree, IMO, performance.
Absolute performance is the determinant at this level, with price being almost a side note.
The threshold is much higher.

The CEO of Oppo determines where a product will fall between these two extremes. When successful, he is able to meet his target audience's performance expectations and price point while sustaining acceptable corporate profits.

So, in all aspects and all ways, the CEO of Oppo daily makes "compromises" that he knows affects the quality of his products. His job is to insure that the "Good Enough" threshold for the Oppo brand is met.

Yes. See above.

Devlon wrote:

I should certainly hope so (although there are exceptions here on CP in both cases)
I also know, however, that they have to know more about the ENTIRE manufacturing/sales process and the necessary art of "compromise" that is involved than some of us. (SEE ABOVE ... AGAIN)

Well, when you get off the fence post, let us know your answer.

Ok, ok I never particularly liked Merry-Go-Rounds, so give me some advice here, lol. What is hard for me to understand is when on both the $10 generic HDMI cable and the 130.00 HDMI Cable (Audioquest Chocolate) state very similar info that says they support 3D Technology, 4K, Ethernet Channel, Audio Return Channel, 1440p and 1080p FullHD Resolution, Transfer Rates of At Least 10.2 Gbps / 340 MHz, 48-Bit Deep Color, HDCP Compliant, and True HD-Dolby 7.1 , etc. What difference will I hear and see on the cable that's 120.00 more? At what price point does the law of diminishing returns zero put? I am willing to try as an experiment in buying just one HQ HDMI cable to see/hear what the difference is. I prefer not to spend 120.00 just to see though unless it makes that much of a difference. Which cable/price point upgrade do you guys think will give me the best audio/visual difference for the money?

I shamelessly use a no name 25' HDMI from cabletrain.com only cost me 30 bucks. Been working flawlessly for 3 years. Staying blissfully ignorant saves me lots of coin!!

In April 2013 issue of the absolute sound they are covering the 2013 Consumer Electronic Show that manufacturers use to demo their new gear. On page 76 they talk about Ethernet cables and how the new AudioQuest Vodka Ethernet cables provide a "drastic" improvement.

"You don't know how much you are missing in naturalness, detail, and focus until you replace your stock Ethernet cable with a good one like the Vodka."

Price is $250/meter

I've been saving this post for a "worthy" cause - it's number 100 and only took me about 6 years to get here. I am in the networking industry - I've worked cat3 through cat6 wire but let's keep it easy - cat 5, 5e and 6. I'm not going to go nuts here but there is a drastic difference in each of these cables. There is also a drastic difference in the material's of these and the material is not isolated to the particular Cat#. You can get great copper/diaelectric in a Cat5 wire and nasty wire in a Cat6 (although not as common as Cat5e). If you take apart each of those types from the same vendor and look closely you'll see differences in the twist ratio and positioning at the connector. All of this to make a cleaner signal so that you can push faster data rates through them.

I run Cat6 wire whenever possible. Is a chunk of Cat6 worth $250/meter? Not likely. Is a chunk of cat6 going to transmit a cleaner signal (and therefore not required to retransmit based on tcp/ip standards - read slower data rate) than cat5. Yep. That you could potentially "hear". TCP/IP would not retransmit bad packets as often (or at all) and you should get a better analog signal as it is getting to the opamp in the correct order quicker.

And F1's Kool-aid is some of the best kool-aid I've ever had.

100!!!

I have heard differences in many types of cables. I can only reason it would be possible to hear/see differences in ALL cables. That doesn't mean every person in every scenario with every cable will hear a difference, but to my ears it has been possible more often than not. The best way to find out is to try it for yourself.

What?! I understood that - I have no argument with that.

Must have passed on and not even noticed...:cheesygrin:

ALL212, first of all congrats on post number 100! Yahoo! I find you post informative. It is interesting to hear a viewpoint from someone in a parallel industry so to speak as it relates to cables. Do you have any required reading/studying in your industry concerning cable design and construction? I think that would be fascinating reading.

Start with a lite study of TCP/IP - would apply to those of us using squeezeboxes and other networkable media players including wireless. http://en.wikipedia.org/wiki/Internet_protocol_suite
Head down to the transport layer description and there you will find the portion that could retransmit.

Wiring specs at http://en.wikipedia.org/wiki/Category:Ethernet_cables. Note the cat5 standard had NO crosstalk specifications. And check out the list of insulations you can use!

They also note that there is solid and stranded available.

Just as with any other wire - speaker, interconnect, power etc., you can also have different grades of network wire.

The TCP/IP part applies ONLY if you use your home network to send music to your system.

Oh - and don't go down to the box store and pay $20 for a 6 foot cat6 wire. If you don't have a local supplier get it on line. As with the rest of the components you can buy there are places that will take your money and laugh all the way to the bank!

All212..
$20 is to cheap for a 6f cat6 cable?
If so how much is a 6F worth?
Now the actual RJ-45 connector at both ends, I'm guessing it does not matter about the quality of it because it's only the wires touching inside the female end correct?

Amazon - 5 foot molded (ends already on it) is under $4. Believe it or not the ends do matter - Cat6 wire has individual channels for each pair and the twists are supposed to go all the way into the end. Cat5/5e ends have no channels for the pairs - you should try and get the twists as close to the end as possible but...

Buy premade cables - trying to terminate Cat6 will put hemorrhoids on your fingers. :eek:

5e is actually 350 Mhz and at that it can carry 1G connections out to 300 feet. Cat6 - same but better interference rejection, the Mhz may be higher but until you start trying to push 10G connections it won't matter. Twists per inch on 5e are varied between the pairs and probably are higher than Cat5 where each pair twist is the same.

My house is poorly run but with cat5e and some Cat6 and running data.

Shielded Cat6 should be some very nice stuff!

For the hell of it, I sent an e-mail to HDMI.org asking one of their engineers to chime in on this. I'm sure it'll get ignored... but I figured it would be interesting if they answered.
