HDMI cables either work or they do not work. Otherwise they are all the same.

Here from Eurogamer
 
http://www.eurogamer.net/articles/digitalfoundry-vs-hdmi
 
and a report from the consumer magazine Which? (can't link as you have to pay for access to their site), found that
 
When Which? lab tested the following HDMI leads, the cheapest lead proved just as good as the most expensive:
  1. A £10 Tesco Value HDMI lead
  2. A £20 John Lewis HDMI lead
  3. A £100 Belkin HDMI lead
Amazingly, our expert viewers saw no difference at all in the picture quality when using the three HDMI leads, with our technical tests confirming identical performances. We passed data through all our HDMI leads at 6.2Gb per second – a data rate more demanding than Blu-ray – without a single error occurring. "
 
Then at Audioholics
 
http://www.audioholics.com/education/cables/long-hdmi-cable-bench-tests/hdmi-cable-testing-results
 
So three tests all of which found that either the cable works or you get sparkles and lines etc which means it is either faulty or too long and you need to get another one. All three tests found no major correlation between price and performance.
 
So we can at least say HDMI for sure and, I would say other digital cables a very likely not be worth spending lots of money on. Mine came from ThatCable off ebay and cost £6.

The digital world is all or nothing.  It either works or it doesn't when it comes to signal.  People thinking a USB cable is going to change the sound of their DAC are really grasping for excuses of why they spent their money on something so stupid.  Same thing with power cables and power conditioners.

RA is down in the Lake District and I have visited the shop. It does refer to mains cables, so another thread is beckoning.....

Watch out because there are actually two categories of HDMI cables, Category 1 and Category 2. There is no snake-oil involved in this.
 
Category 1-certified, or "Standard" HDMI cables, have been tested at 74.5 MHz (good for resolutions such as 720p60 and 1080i60)
 
Category 2-certified, or "High Speed" HDMI cables have been tested at 340 MHz (appropriate for resolutions such as 1080p60 and 2160p30).
 
So if you have a Full HD (1080p) or higher video source and display, you ought to make sure your HDMI cable connecting them is a High-speed or Cat-2 certified one.
 
Check the section "Cables" on the HDMI wikipedia entry: http://en.wikipedia.org/wiki/HDMI
Or check the HDMI FAQ pages themselves: http://www.hdmi.org/learningcenter/faq.aspx#49
