Q: Between optical and coaxial, which connection is going to give the better sound quality, and why?
A: " Better" is relative. In a harsh environment, optical may have advantages. By "harsh" I mean:

Cable runs over 10ft
Cable runs in close proximity to video and power cords emanating RF noise
In most cases, the above conditions would result in negligible impacts on the signal quality since the signal being transmitted (PCM or bitstream) is sampled at low frequencies (44-48KHz) and thus are more immune to noise impairments.

However, using optical cables can minimize the potential of the above mentioned problems and thus may help to reduce common mode noise. The only negative about using optical cables is the connection is not always as secure as a coax one, and can sometimes be compromised easily by moving components frequently. In addition, optical cables are usually more expensive than coax ones.

Bottom Line: Using optical cables for your digital connections may help minimize susceptibility of coupling RF noise into the line and reduce loss for long runs (10 feet or more). However, optical cables tend to be more costly and sensitive to abrupt external forces, which may potentially weaken the connection over time. In any event, either connection method should yield excellent and comparable results in most cases.
------------------------------------------------------------------------------------


So basically digital coax, like any other RCA-type cable, is susceptible to RFI or EMI... meaning a better cable sometimes (but not always) will yield better results.

True, but you still don't need to buy Monster products in order to get a good quality optical or coax cable.

Ahh, just like you don't have to buy a 60" Pioneer Kuro Elite to have a good quality Plasma. Some people just want the "best".
I'm actually a little jealous of his z-series purchase, having just upgraded all of my HDMIs to M-series (bought on ebay for $40 each). I'm in the process of doing the same with my Fiber Optic, Sub, and Component cables. You can try to talk me out of Monster, but my brain's been washed, I somehow started to believe the hype.

Fair enough... you like Monster... but they are FAR from the best. There are many other lesser known brands out there selling a better product at a higher price.

That is correct, when referring to a digital cable like Firewire, DVI and HDMI.
It is NOT correct when referring to Digital Optical or Digital Coaxial cables, sorry.

So in your little world where the laws of physics don't seem to apply, how does that "data" on an HDMI connection get to it's destination?

Here on planet earth, even an HDMI connection uses electrical conductors to carry electrical impulses that correspond to the digital data stream. This is no different than a "digital coaxial" cable that uses electrical conductors to transmit electrical impulses that correspond to a digital data stream.

A digital cable is really a misnomer. It just indicates that the cable is intended to carry electrical impulses for an encoded digital data stream. You are correct in that the electrical impulses themselves are an analog transmission method. However, you overlook the fact that DVI, HDMI, "digital coaxial", USB, IEEE.1394, etc. all use this same method.

Therefore, a "digital coaxial" audio cable is every bit as much a digital connection method as an optical cable, or an HDMI cable.

That's irrelevant, it's still digital data, the digital coaxial cable is not.

Actually it's completely different. One is data, one is electricity, one is light. By definition one is digital, the others are analog.

By that definition yes, but I would hope that the knowledge that data is electrical doesn't need to be stated. Everything in life is analog! Where the term digital is used refers to the packages that are being delivered. With HDMI, DVI and Firewire cables it is digital, with the others it is analog, hence digital coaxial and digital optical are analog cables, HDMI/DVI and Firewire are digital.

Arguing semantics makes you look arrogant.
I'm not trying to look arrogant or impose anything on anyone. I responded to the original poster to try to reduce the amount of misinformation that might be relayed to other readers of this thread. I never came here looking to start an argument. I apologize if you think I am trying to argue semantics.

However, I still have a hard time understanding what you are talking about. Your response above basically comes across to me that you think physics is irrelevant. I just don't see how you can make a statement like that and think that anyone will take any of your other information seriously.

Further, "data" is defined as "information." It is not a transport method. the "data" still has to be transported to a recipient by some method that follows the laws of physics. This is why I can't understand how you can compare "data" to electricity and light. The "data" still has to be transported by moving electrons in an electrical conductor or via pulses of light in an optical conductor.

Please help me understand what you mean when you say that the digital "data" streams are no longer digital data streams when using a coaxial or optical cable but yet they can still be digital data streams if they use an HDMI cable.

Anyways this cable is built really good as all Z-Series cables and when I hooked it up & threw in Nickleback new cd and Bamm the Bass extention is more difine than before, and the overall sound is just so much better, I am very happy with this improvement and would recommend it to any one using a Digital coax cable, for audio , and the price is very fair compared to alot of other brands out there, actually pretty cheap..LOL,,
So....your 1's and 0's are higher quality than my 1's and 0's? Digital is digital no matter if you use a $2 coat hanger or $200 monster cable. The signal either gets to where it is going or it doesn't.

Digital coaxial isn't digital guys.
Only DVI, HDMI and iLink are digital.

Are you serious? You contradict yourself with your own post. Perhaps you should read up a little more on the technology.

I would NEVER buy monster cable for a outrageous price. The majority of the money consumer are paying is going to the advertisement not the suppose quality of the cable. I'll pay for a monster brand cable if it was the same price range as MONOPRICE cable. Believe me, I know because I HAVE monster cable that I acquire for free, the sound difference from my standard no name brand cable vs monster, I cannot hear the difference. If I do buy monster cable, I'll buy it for $10 or less. That is how much I think they are worth. JMO!

oh.... you better believe my 1's and 0's are way better than yours, well at least they cost about $100 more than yours.

Ahh leave him alone guys. If he's happy, let him be. It's like a guy saying he's happy with his Sony STR-DG720 and clowning him saying he should have gotten the Onkyo 606 or whatever. If he's happy, let him share.

So your just saying that your 1's are followed by a few more 0's than his!

Man, I'm even a Monster Fanboy and I couldn't resist.
