i dont know if i saw it on here or not, but the HDMI cables are video + sound, so no need for the extra cables if you dont want them. i have the hdmi + digital audio for my ps3 + hdtv. i didnt see a difference in quality with the digital audio cable, but i dont have any special speaker setup, just larger PA speakers.

you can get some nice digital audio + hdmi cable packages once in awhile on the Internet for a really nice price. (maybe like buy.com or ebay) i know i got my hdmi cable from buy.com for like $10 shipped. there isnt a huge jump in quality for the more expensive ones. normally the short ones, weather cheap or expensive, will have the same quality. the longer ones, (+6ft) needed to be a larger wire, and a higher quality material all around, but still no need for the cables that are $50+ ) the expensive ones are normally just jacked up in price because they know people will by expensive stuff if they don't know what is special about it. the only major difference is that some of the expensive ones are shielded, which basically protects the cables from surrounding electromagnetic waves. to be sheiled means it have a thing piece of grounded metal, like tin foil, raped around the wire to protect it from electromagnetic waves in the air. these cables (and every cable that isnt used for power) must stay at least 2 inchs away from your power sources (wires for the tv/ps3/audio receiver, or the receptical in the wall itself) basically if you have any cable withing 2 inch's of an ungrounded powersource, that cable weather it is telephone, hdmi cables, audio cables, or just a low voltage wire, will have nasty side effects from the power cable. reason being, the power cables use AC type power, the AC power natrually uses 60 Hz (50Hz euro). these frequencies radiate from the wire and can effect surrounding things. normally they are harmless or to weak because there is a ground within the 2 inchs that obsorbes the electromagnetic waves, but if there isnt, the smaller , non-power cable will absorb the waves.

when a power cable is close to audio, you can here a buzzing or ringing sound. this is most popular with unprofessional car audio installations. people might have spent whatever amount of money either changing there head unit or installing amps, and now they hear an annoying hiss in there speakers. this is the Hz of a power cable effecting a non-shield audio cables. same with telephone, if its not 100% perfectly clear, there is a power cable in the wall thats to close to the telephone wire. i would imagine the same goes with HDMI cables. the stores mark up the shield cables because then they can brag that it will remove any poor picture that a cheap one causes, but basically the cheap on is just to close to a power cable.

Solution:
a cheap fix if u can not get the cable out of the 2 inch radius of a power cables, just rap the cable in tin foil or other metal, and for best results, ground the wire to the outlet or radio.

basically, take the thin metal and rap a thin layer around the hdmi or audio cables that are to close, and then strip solid wire (only needs to be like 22 - 16 awg wire) and wrap the wire around the metal,(just enough to keep the metal around the wire, nothing special). then, either loosen a screw on the back of the radio, remove the paint on the screw or the metal, and ground the wire that way, or ground the wire with your outlet. it might seem like i have smoked something before hand, but this is the cheapest and most practical way to protect your cables.

if you don't have protected cables, you can destroy your tv or speakers over time. basically extra voltage is leaking into that sensitive wire from the power cable throw the air. the extra voltage might be meaningless, but if the power cable would draw alot of power, or generate alot of power (like a car, or amp) then the extra power will be to great, and probably wreck a few things.. in most cases you shouldn't be effected because most larger cables have a ground included in the power cable. the ground is not only used for a protecting against a short circuited, it also removes this extra voltage that emits in the air.

and, if u do anything like TIfreak, and put neons under the tv or radio (or even if u are just installing them in your car) U MUST MAKE SURE that if there is a wire going from the light to the transformer, it is FAR away from any audio cables. these wires, if used in AC or on a car, will generate crazy electromagnetic waves if u are to close to them.. =]

if any one else has a question concerning audio + video , weather home or car, let me know =]
