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. |

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. |

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. |

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. |

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.
