This cable is so insane!4 Posted by: from: on I bought this cable about 3 days ago and it's probably the best investment i made since the time time I bought clothes for my dogs! Using my old HDMI cable from my TV to my PS4 was pretty boring, i felt like the games were just making my life even more miserable than usual, but now that I have this amazing cable, I CAN TRAVEL BACK IN TIME! In fact, I am writing this review in the past (it's the past for me but present for you). I could not give 5 stars because I don't have enough money to buy another one to go back to the present (the future for you). TOTALLY WORTH IT THOUGH!

You have to spend money to make money!!!5 Posted by: from: on At first I was sceptical about the price. Boy was I wrong! This bad boy pays for itself in no time at all! I had a choice between paying rent or getting this cable and I am glad I made the purchase. This cable is 3.3 feet long! Most people don't understand the advantage this cable gives over your standard $30 HDMI cable. It runs everything more efficiently! My TV, My computer monitor, my blender! everything! I save cents on my electricity bill each month! Using this cable and a standard blender, you can grind down 1 maple tree for 4 jars of maple syrup! Hook up 2 cables to the blender and BAM 16 JARS! The rate of increase is exponential. That is money made right there! Best investment ever made! I am now the 3rd largest distributor of maple syrup on my street! A must buy for first time investors.

The best around Nothing ever gonna keep it down5 Posted by: from: on Bought a new 4K TV but was disappointed with the quality of my old VHS tapes. Hooked this baby up to my tv.. Presto! Back to wacking it at least 3 times a day. This cable is a must buy, worth every penny!

Great Scott! What a Cable!5 Posted by: from: on This is the only cable that can provide the necessary bandwidth for displaying real-time readouts from my Flux Capacitor since I updated the multi 8 bit LED display to 4K. An unexpected side-effect in updating the display was realizing that I only needed to hit 87.5 MPH before, and I had been rounding up unintentionally this whole time. The lower speed threshold correlated nicely into a reduction in plutonium requirement. I don’t think I need to tell you, but the cost savings in my monthly plutonium bill has more than made up for what seems to be an initially high price for a cable. I’ve been using this cable for 47 years, and can tell you, these things are made to last!

Stunning Upgrade5 Posted by: from: on I was amazed at the power this cable has. It worked perfectly on my super high def wall hung flat screen LECD Plasma monitor. But wait. Believe it or not, with a few minor modifications (aluminum foil, epoxy, etc) I now have perfect 1080p images on my toaster oven! So cool! Next step? Modify to plug into my old-school Pegasus Equine Shield. Pics when I finish!

Great cable for the money!5 Posted by: from: Bloomington, MN on I bought this cable to hook up my recently purchased a Dynex 19 inch color LCD 720p HDTV (WIDESCREEN!). My TV/VCR combo had served me well for many years and I felt it was time for an upgrade. I was disappointed that my new TV did not have VCR playback capabilities, but I was able to retain the ability to play VHS tapes by incorporating the old TV/VCR combo into my setup as a stand for the new Dynex! I researched HDMI cables for several weeks, reading reviews and watching unboxing videos. My friends recommended that I just buy an inexpensive cable and started spewing techno-babble at me about how HDMI cables work. They claimed that it's not possible for a higher priced HDMI cable to improve picture quality because of how digital video signals work. Something about 1s and 0s and error correction. I was skeptical. I mean my friends are very smart, but they aren't Best Buy employee smart. So I went to my local Best Buy to speak to the experts that I trust. A while back, my computer would not boot into Windows ME and instead displayed the message: "Boot Device Not Found." I thought perhaps the hard drive had become disconnected. Well, I'm glad I took it to the Geek Squad. The technician saw the error msg and was able to determine that I needed a new hard drive without even opening it up or running any kind of diagnostic software. What technical expertise! But let me get back to the cable. I told one of the customer service agents about the my home theater setup and my intentions to hook up my gaming console to my new 19 inch color LCD 720p HDTV (WIDESCREEN!). He recommended this cable for its inherent ability to increase the resolution and frames per second in games. So I bought it and brought it home. I went to the living room to hook up my console and I hit my first snag. Nowhere in the documentation did it specify where to hook the cable up to the NES. I was about to give up but I noticed a cover on the bottom of the Nintendo. It turns out that this is where the expansion port is located which is where you connect the HDMI cable. I hooked the other end up to the TV and fired up the NES. Unfortunately, I didn't get a video signal. After much experimentation I figured it out. To get HD output from an NES you have to hook up the analog outputs as well. Apparently the TV combines these two signals to form an image. And what an image! The blacks were so deep that it desaturated all the color from my living room furniture! I had been meaning to apply a darker stain to my coffee table and now I don't have to! My couches were now black, giving my living room a much needed neutral color scheme. Super Mario Bros looked amazing! I hit the info button on my remote and discovered that it was running in 4k 480Hz with a perfectly matched frame rate of 480 frames per second! I wanted to capture some game footage so I hooked the NES up to the VCR. I've never seen such clarity in a VHS recording! It makes Blu-Ray look like an Etch A Sketch! I now realize why my friends were trying to dissuade me from buying a mid priced cable like this one. They probably purchased some cheap $500 dollar cable and didn't want me to get an HDMI cable with over twice the performance of their cable. I no longer speak to them as I don't need people like that in my life. All my friends now reside in the Mushroom Kingdom. One other thing to note is the the Zapper didn't work with the new TV. This is most likely because the Zapper could not detect if it was hitting a target due to the increased resolution and frame rate. While the documentation leaves room for improvement as hooking up an NES wasn't even mentioned, at this price point I can't justify taking away a star. FIVE STAR PRODUCT!!! If I had any friends left, I would definitely recommend them this product!

Worst cable I have ever purchased1 Posted by: from: Santa Barbara, CA on I've recently been wanting to upgrade my current TV setup to this new "HD" technology I've been hearing about. I'm quite happy with my current TV setup as it was less than 10 years old. So I decided to upgrade my connections to "HDMI" using this so-called superior cable. I got two of them because I needed at least 5 feet from my TV to my tape player. The first problem I had was joining the two cables together. No matter how hard I tried they wouldn't fit together. So I ended up moving the TV closer to the tape player so I could end up using one cable. When I go to connect the cable to my TV I tired every connection and every angle but this cable wouldn't fit. I tried with both cables with the same result. I called my TV manufacturer to see if I'm missing something and was advised I need to purchase A BRAND NEW TV because my model doesn't have that connection. Same deal for my tape player, except they don't make one for this connection. It's like saying "these tires make your car go 300mph but oh they only fit on a BUGATTI and not on your toyota prius. I went to best buy upset and wanted my money back but was refused but there appeared to be negligent damage to the cable ends and that they have never seen this happen. I explained this happend when I was tried to get the cable to fit into my TV and tape box but they wouldn't hear it. Anyways there is a silver lining to all this. I scored one side of the cable with a knife and flipped the cable inside out. I pulled the gold wiring out and made my own RGA cable with that wire. I took the diamonds to a local jewler and for a small charge he made them into a diamond necklace for my wife. Now everyone's happy!

ACTUALLY FILLED WITH DIAMONDS!5 Posted by: from: on At first I was hesitant to pick up such an expensive cable for my new HDTV. My wife pleaded with me saying "Why are you spending more money on the cables than you did on the TV?" Well who has the last laugh now? When I first opened the packaged I was surprised how heavy the AudioQuest Diamond 3.3' High-Speed HDMI Cable was, it almost pulled the TV down off of the wall, but I assumed that was just quality manufacturing. A few hours later when the shear weight of the cable brought my television (along with the wall mount and drywall) crashing to the floor did I really see the value of the AudioQuest Diamond 3.3' High-Speed HDMI Cable. When I sifted through the rubble I noticed the HDMI cable had been ripped and diamonds were poring out onto the floor! I quickly scooped them up and brought them to the nearest pawn shop! I was told the diamonds had a value close to $25,000 but since they needed to be framed and would sit around the shop for a while we negotiated down to $1500, an almost $500 profit! I spend my days now going from Best Buy to Best Buy in search of more AudioQuest Diamond 3.3' High-Speed HDMI Cable. My pawn shop guy continues to buy the loose diamonds from me, it's a wonderful arrangement. I think I'm going to be able to afford a PS4 and Xbox One for Christmas this year!

Oooooooh, my!5 Posted by: from: Elk Mound, WY on OK, I know, some of you are thinking, this is a digital cable, and that HDMI standards have checksums and parity bits and such to make sure that the digital digits being received by your TV are identical to the digits sent by your player... so that therefore there should be no difference between a $10 digital cable and a $1,000 one... BUT: THIS digital cable is special! Somehow, it smoooooths those pesky digits, making the 0s a little rounder, and the 1s a bit less pointy on top. This results in increased pacing and slam, with less graininess! Pop this puppy on your DVD player and tell me I'm wrong! Well, after you re-attach your head because it will have been blown away!
