I'm with arny on the ground loop thing.

My brother had a Monster Cable that was so big that it broke the little door where the cable plugs into. He now buys from Monoprice.

(LCD - Sony KDL - XBR4) (Receiver - Sony STR-DA4ES)(Blu Ray - Oppo BDP-83) (PS3)( Dish Hopper DVR With Sling) Speakers (L & R - Paradigm Studio 20) (Center -Paradigm CC-470) (Surrounds & Back Surrounds - Paradigm SA-15R in walls) (Subwoofer 1 - Sunfire HRS-12) (Subwoofer 2 - Paradigm PW-2100)

That's great...now how is anything you've said related in anyway to what I posted?

I understand that you feel the need to grandstand, that's evident in almost all of your posts, but maybe you should have randomly quoted someone else in order to shine the spotlight on what you think are your great "achievements".

I'll throw you a bone, why don't you tell us all, great wizard, how S/PDIF is different from S/PDIF?

You asked me a question and I answered. That is, whether I know the answer or not. Don't ask me questions if you don't want the answer.

No, I feel like stopping people from making voodoo scientific statements as to stomp on people to feel good. You know, like this:

If someone said a thicker cable sounds better, you would ask them to prove it. You claimed S/PDIF coax is the same as S/PDIF toslink. I ask you to demonstrate how you know that, and what data you have to back it. So far you are refusing to do what you ask others.

You are playing a game of Calvinball. For those who don't know what this is as well as Sam, here is the wiki on it: http://en.wikipedia.org/wiki/Calvinball#Calvinball

These are the rules:

"The Unofficial Official Rules of Calvinball

Permanent Rule: You may not play the Calvinball the same way twice.

Primary Rule: The following rules are subject to be changed, amended, or deleted by any player(s) involved. These rules are not required, nor necessary to play Calvinball.

1.0. The following words in these rules are mostly freely interchangeable, the Primary Rule applies:

Can

May

Must

Shall

Should

Will

Would"


In other words, you change the game as you go along. You did not say that. You said this:

All of a sudden you take out the highlighted Toslink out???

So do you know the answer to the question or not? You called him a fool for not knowing. Do you know the answer?

P.S. This is my favorite line from Calvin and Hobbes:

Calvin: "Dad, are you vicariously living through me in the hope that my accomplishments will validate your mediocre life and in some way compensate for all of the opportunities you botched?"

Dad: "If I were, you can bet I'd be re-evaluating my strategy."

Calvin to his mom, later: "Mom, Dad keeps insulting me."

Let's hope your next response doesn't follow this kind of logic smile.gif.

Let's see. S/PDIF is a protocol for sending digital audio data. The protocol does not change based on the physical transmission interface. S/PDIF works the same over optical, digital coax, and HDMI. There may be slight changes in output based on the type of transmission. But, what does that have to do with S/PDIF?

I didn't ask you anything, and you didn't answer. You posted another question. You're not always the centre of attention .

Now you post a huge diatribe designed to make you look intelligent, and you've failed, once again. You still haven't answered anything.
I don't think you really know.

The S/PDIFdata transmitted by a coax cable is the same data transmitted by a toslink cable. In one case it is represented by an electrical signal, in the other it is represented by pulses of light. It's quite simple.....google it, you might learn something.

I think it is safe to say that the transmission format over HDMI is vastly different than it is over coax and optical, which are as you say: practically identical. HDMI audio is interleaved with HDMI video. SP/DIF audio stands alone.

How identical are SP/DIF over optical and coax? The only difference between coax and optical in audio equipment is the hardware right by the I/O port. For coax its an electrical line driver/receiver, and for optical its an optical line driver/receiver. The signals merge in the logic and control circuits in the equipment. The output ports are usually simply wired in parallel. The input ports usual go into a simple selector switch, either mechanical or electrical.

The technology in question evolved right before my eyes. It was revealed to me by a stream of magazine articles and technical papers that were written before, during, and after its introduction. It all made wonderful sense to me because I had been involved for years before with digital data transmission between mainframe, mini and micro computers. The first piece of digital I/O gear that I worked on, hands-on and internally was an IBM 729 tape drive that was implemented with discrete transistor logic.



So, it was all right there before me, in detailed logic diagrams, in real hardware whose circuits were physically quite large, and in signals that I probed with high speed oscilloscopes, etc.



Notice that the circuit cards carried discrete transistors, diodes, resistors capacitors, etc. Card level repairs were possible in the field. The logic diagrams for the machines showed the interconnections, and had appendices with diagrams of the various kinds of cards in the particular machine. Most machines used a fairly small selection of different card types. Old timers can read the resistor color codes and see that 4.7K was a common resistor value. This was probably RTL logic. This is circa 1960s technology.

The first CD players and digital recorders used off-the shelf TTL ICs and some higher level application specific large scale ICs, which was typical for the late 1970s and early 80s.



This is the wiring that routed signals and power among the circuit cards. The ends of the silver-plated OFHC wires were wrapped around silver-plated pins that terminated sockets pins for the PC cards shown above. While assembled by automated wire wrapping machines that were driven by decks of punched cards, the wiring could be and was frequently changed in the field using simple hand tools.

I seem to recall giving a presentation about CD audio technology to my local AES chapter before the public introduction of the CD. Our chapter was was populated by at least two AES Fellows - both serious technical heavyweights. Everybody was quite happy.

fwiw, Parts Express is located in Ohio, and I choose cheapest/free shipping and it comes so quickly.

Buy the size you need, anyone of the below will suit you just fine, heck I have 2-3 each optical and HDMI as "spares" just for swapping stuff around, so cheap price.
Don't over think this too much, many-many more things in life are so more important....

The first 6 responses summed it up. No need for the sarcasm.

No - really it's hump day Wednesday, and seriously these side bars in threads I truly enjoy!
Pick up tid bits at times, others just some of the virtual banter/humor also....
