Speaking of power cords....I ordered one from Monoprice to use on my Sony 55ES because the one that came with it is kind of long. The Monoprice one appears much thicker. (lower gauge wire?) Is it OK to use with my projector?

This is in contrast to analog cables (Component/RGB) where there was a continuous curve of varying quality between perfect picture, and no picture. Actually there was no analog cable that would give you perfect picture, every analog cable degrades quality, it's just a question of how close to perfect you could get.

I have a seperate 15 circuit for the lights, and 4 seperate 20's for the audio and video.

For my home theater setup, I have 2n x 3 power coming from 6 different electric companies with diverse entrances and a separate generator for each power plant. However, my projector runs off two AA batteries.

Not sure if it does or not, but I have a $100 power cable going to mine just to make sure... smile.gif

Placebo is very powerful.

But I do know for a fact cables can make a difference. Have done a lot of double blind tests on analog and digital interconnects, as well as speaker cables.

But... all my testing was done with high end two channel audio.

Not Video.

I don't think we are as perceptive to video changes then we are to audio changes though.

With music only, you are only really engaging one of your senses, with Video you are engaging at least two.

And the more stimulated your senses are the less you notice differences.

Example: When I watch a 3D movie I can't concentrate as much on how "great" the sound is compared to when I watch the same movie in 2D.

Human limitations I guess.



Very easy for anyone to test what I am talking about. Close your eyes during a movie and you'll quickly notice how much more perceptive your hearing is of the source material.

Cloverfield sounds Amazing with your eyes closed.


To anyone on the forum that has the money and space for a high end two channel setup, you should do it. It can be some of the most emotional and amazing experiences you have in your life.

Turn off the lights and let the emotion of the music consume you.


I miss having a high end two channel setup, but will figure out a way to get the space for one again within my life time.

I think it is exactly the opposite, I think we are FAR FAR FAR more perceptive to video changes than audio changes.

Could be.

But I've never done a blind test of power cables or hdmi cables for video.

I think those changes are harder to pick up on video then audio.


You have a high end audio system, you should know.

I'm talking about changes in cables, not speaker to speaker or display to display.

Oh I think I misunderstood you than. I thought you were generalizing saying that it is easier to pick out changes in detail with audio than video. I think when you are comparing cables both audio and video are EXTREMELY difficult. You're better off using something like an o-scope or test patterns to see if anything changes. Unless you are using cables that have no business being in their application (not rated for the power load or length) you'd be hard pressed to find a lot of difference. I want a well constructed cable that is rated for the load I'm using, I don't need anything real fancy. There are some spectacular outfits for getting great cables at fair prices. I am a big fan of Bluejeanscable.com but there are more. Bettercables.com and Accell are both brands that I've used that I like, I still use Accell for my HDMI cables as they've been flawless for YEARS regardless of what I put through them. The HDMI cable I installed to run to my projector from Accell was installed nearly 8 years ago. It still passes everything I throw at it, including 4K content. Not a single hiccup to date.

I am using a trusty Monoprice HDMI at 75 Feet and it supported 4K at 60 htz... smile.gif

I was really worried I was going to have to go to Fiber Optic HDMI.

Lets say I just bought myself a bunch of fancy cables and I have 1400 dollars left to buy an AVR or Separates. Audio ,specifically surround sound, is the number one on the list, I run my HTPC and STB through my OPPO 103 so I only use my current AVR a Yamaha 673 for sound. If there is an AVR that has better video processing then the OPPO then that would be a huge factor, but i assume all 4K upscaling is about even.

I will say this though... Power Cables are one of the FINAL investment places you want to spend big money.

Even in the High-End Audio World, Power Cables and Power Conditioners (assuming your power is not crap to begin with) differences are so subtle. The Equipment / Room first, "High-End" power cables last...

Key word is "differences", not that a high cost one is better...

Yup, you should only buy one after you've already got all the content you will ever want to buy biggrin.gif
