5.0 out of 5 stars A cynic knows the price of everything and the value of nothing, 20 Mar. 2010
Verified Purchase(What is this?)
This review is from: Wired-up HDMI Pro Gold, HDMI TO HDMI Cable With Ethernet (Accessory)
Comments from an electronics research technician. Independent laboratory tests demonstrate measurable quality differences between cables. It particularly identifies the cheapest cables which are sometimes not properly shielded and which can contain copper plated wire rather than solid copper.
But the issue is not whether differences exist but whether they affect the user. And in practice the average person lacks sufficiently acute senses to detect those differences even when inferior cables are used to connect high quality audio and video equipment. Without the use of test equipment I can rarely make that detection, and I have an in depth knowledge of the science and what to look for.
Also loss is most detectable in longer cables e.g. 5 metres plus. These cables are only 1 metre in length.
I bought these cables to connect my son's HD Sky Box to an HD TV. Their performance proved perfectly satisfactory even when I compared them to my own high quality professional cables. My conclusion. Excellent value for money. I genuinely recommend them for any home user.

Thanks for a great review - perhaps its wise to have a few cheap cables from different manufacturers to enable glitches caused by them to be quickly pinpointed. Shame there is no test equipment to show up differences between £140k pa Cameron's Big Society and claptrap

There are of course measurable differences between cables and this will include two cables of the same brand and model. That is not however relevant to picture and audio quality assuming the data reaches the receiving end. Either the data gets through or it doesn't. You have written "And in practice the average person lacks sufficiently acute senses to detect those differences (between different quality cables)" but there is in fact NO difference. If the data gets through it gets through - period.
There are only two caveats to this:
1. In an electrically noisy environment shielding can prevent signal interference (and so data corruption) so that a shielded cable may work where an unshielded cable may not. The most basic shielding is generally sufficient in a typical home environment

2. VERY cheap cables can be physically flimsy and liable to breakages

It is theoretically possibility that a signal is borderline and so the occasional bit is dropped. This would result in freezing or obvious picture/sound corruption. Effectively this is a situation where you would consider the data not to be getting through to the other end of the cable as I described above.

I am an electrical engineer and design digital circuitry and interfaces as part of my work.
